America, 1920–1973: Opportunity and Inequality

How this unit works

This is your Paper 1 Section A period study (option 1A/D): 40 marks, about 60 minutes, six questions, no SPaG marks. Questions 1–3 are built on two short written interpretations printed in a separate booklet and carry 16 of the 40 marks — so alongside the facts, you need to know where historians and contemporaries disagreed, because that is what the interpretations will be about. The question methods live in the Exam Skills section; this unit supplies the knowledge.

The five questions this unit answers

1. What made the American economy grow so fast in the 1920s — and why did that growth leave so many people out?
2. Why did the world's richest economy collapse, and how far did the New Deal repair it?
3. How did the Second World War change America's economy and its society?
4. Why did the civil rights movement achieve so much in law and so much less in economic life?
5. The spine: across the whole half-century, did opportunity widen faster than inequality narrowed?

Chapter 1 — The boom and its shadow, 1920–1929

America came out of the First World War richer than any country had ever been, and spent the next decade behaving as though that condition were permanent. This chapter explains how the boom was produced, what it changed in ordinary life, and — running alongside all of it — who it never reached. The two halves are not separate topics: the same policies and industrial methods that generated the prosperity also concentrated it, which is why a chapter about a boom has to be a chapter about inequality as well.

1.1 How the boom was engineered

Between 1922 and 1929 American industrial output roughly doubled. That did not happen by accident. Two forces combined: a government that deliberately stood back, and a manufacturing method that made goods dramatically cheaper.

• Republican policy. All three presidents of the decade — Harding, Coolidge, Hoover — believed government's job was to create conditions for business and then get out of the way. In practice: laissez-faire (minimal regulation, weak anti-trust enforcement, hostility to unions — which were weaker in 1929 than in 1920); tariffs — the Fordney–McCumber Act (1922) raised duties steeply, protecting American producers inside their own vast home market; and tax cuts — Mellon cut the top rate of income tax from 73% (1921) to 25% (1925), arguing money left with the wealthy would be invested.
• Mass production. Ford's moving assembly line (Highland Park, 1913) broke car-building into small repeated tasks performed by semi-skilled workers as the chassis moved past. Assembly time for a Model T chassis fell from over 12 hours to about 90 minutes. Ford passed the saving on in price — the Model T fell from about $850 at launch to under $300 by the mid-1920s — and in wages: $5 a day, roughly double the going rate, partly to cut the crippling labour turnover repetitive work produced, and partly because well-paid workers could buy cars.
• The multiplier. Every car needed steel, glass, rubber, leather, paint and petrol; every driver needed roads, garages, filling stations, motels. Cars registered rose from about 8 million (1920) to over 23 million (1929). Mass production then made radios, refrigerators and vacuum cleaners cheap enough for a mass market — and around two-thirds of American homes had electricity by 1929, creating the demand for them.

1.2 A consumer society

Producing goods cheaply is only half of a boom — somebody has to buy them. The 1920s invented the techniques for persuading Americans to want things, and for lending them the money to buy them. Advertising became a professional industry, moving from listing a product's features to attaching it to an aspiration — status, romance, modernity, being a good mother. Advertisements filled the mass-circulation magazines and, from the early 1920s, the radio, which spread from around 60,000 households (1922) to roughly 10 million (1929). National brands replaced local ones; chain stores such as Woolworth's brought the same goods to small towns as to cities.

The financial mechanism was hire purchase: instead of saving first, a family took the washing machine home and paid monthly. By the late 1920s an estimated three-quarters of cars and a large share of furniture, radios and appliances were bought this way. Its effect was to bring demand forward — converting future income into present purchases, which is why consumption ran ahead of what wages alone would have supported. The goods reshaped domestic life: electric irons, vacuum cleaners and washing machines cut the hours of housework (while raising expectations of cleanliness); refrigerators changed how families shopped and ate; and above all the car altered where people could live and work, making the first large suburbs possible and giving young people a private space beyond adult supervision.

1.3 Who the boom left out

This section exists because the option's title is Opportunity and Inequality, and because almost every interpretation question on the 1920s turns on whether the prosperity was general. It was not. Knowing precisely who missed out, and why, lets you argue either side of that debate with evidence.

• Farmers — the largest excluded group. Their problem was the opposite of everybody else's: they produced too much. Wartime demand had encouraged more ploughing and machinery bought on credit; when European agriculture recovered after 1918, the export market shrank while output stayed high. Prices collapsed in 1920–21 and never recovered; agriculture's share of national income fell from roughly 16% (1919) to about 9% (1929); debt and tenancy rose, and around six million people left the farms during the decade. The Fordney–McCumber Tariff made it worse: other countries retaliated against American farm exports, and farmers bought their protected machinery at protected prices.
• The “sick industries”. Coal lost ground to oil, gas and electricity; New England's textile mills moved south for cheaper non-union labour, or closed; shipbuilding contracted. Workers in these industries experienced the 1920s as a depression, and their strikes were consistently defeated.
• Race and region compounded it. Roughly two-thirds of African-Americans still lived in the South, many as sharecroppers whose incomes depended on cotton prices and whose debts were held by the landowner. Mexican-American and Native American communities were poorer again.
• Inequality inside the boom itself. Even in expanding industries, wages rose more slowly than profits and productivity, so gains concentrated at the top: contemporary studies suggested around 60% of American families had incomes below the level then thought necessary for basic necessities, while a very small group at the top received a share of national income comparable to the poorest 40% combined. This is the single most useful fact in the unit for testing an optimistic interpretation of the decade.

1.4 Speculation

By 1928 a growing number of Americans had discovered that money could be made faster on the stock market than at work. The Dow Jones index, around 100 in the mid-1920s, reached 381 on 3 September 1929. Some of the rise reflected real profits in real industries. Much of it did not: prices increasingly reflected the expectation that prices would keep rising — the definition of speculation. Two features made it dangerous. Buying on the margin: an investor could pay as little as 10% of the price and borrow the rest from a broker, using the shares as security — multiplying gains and losses identically, and meaning a price fall triggered an immediate demand for the balance. Brokers' loans rose from about $3.5 billion (1926) to roughly $8.5 billion (late 1929). And breadth: perhaps 1.5 million Americans held shares by 1929, many of them small investors with no understanding of the companies they owned. Warnings existed — earnings lagging prices, construction slowing since 1926, car sales levelling, the Federal Reserve raising rates in August 1929 — and were ignored, because the market had rewarded optimism for years.

1.5 Mass entertainment

The 1920s is the first decade in which most Americans shared the same entertainment. Cinema was the largest of the new industries: picture palaces seating thousands opened in every sizeable city; weekly admissions ran into the tens of millions and roughly doubled over the decade. Hollywood's star system turned actors into national figures whose clothes and behaviour were copied. Silent film needed no shared language — which mattered in a country of millions of recent immigrants; The Jazz Singer (1927) introduced synchronised sound, and within three years silent film was finished. Radio spread faster still and did what cinema could not: it brought the same programme, advertisement and music into homes across the country simultaneously (national networks: NBC 1926, CBS 1927). Sport became mass spectacle the same way — Babe Ruth and Jack Dempsey were famous to people who had never seen a game or a fight.

Jazz was the decade's most distinctive cultural export, and its history is inseparable from the Great Migration (see 1.8): developed by black musicians in New Orleans, carried north to Chicago, Kansas City and New York, it became the soundtrack of white urban youth in the speakeasies (1.7). In Harlem, the concentration of black writers, musicians and artists produced the Harlem Renaissance — Langston Hughes, Duke Ellington, Louis Armstrong — the first time African-American culture achieved that national visibility. The relationship was not equal: black musicians created the music while white bandleaders and record companies took most of the money, and famous Harlem clubs performed to white-only audiences.

1.6 Women in the twenties

The flapper is the most familiar image of the 1920s and one of the most misleading. The real constitutional advance came first: the 19th Amendment (ratified August 1920) gave women the vote after a campaign of more than seventy years. Its immediate political effect was modest — women did not vote as a bloc, few were elected, and the organised movement fragmented once its unifying goal was won. Some changes in daily life were substantial: appliances cut housework hours in electrified homes; women in paid work rose from roughly 8.4 million (1920) to about 10.6 million (1930) — though their share of the workforce stayed at roughly a fifth, concentrated in low-paid clerical, retail, teaching, nursing and domestic work, usually left on marriage; divorce became more common; family sizes fell; and women took a growing share of college places.

The flapper belongs to a much smaller world — young, urban, single, usually middle-class or wealthy. Shorter skirts and bobbed hair, cosmetics, smoking and drinking in public, dancing to jazz, driving, going out unchaperoned: real, and shocking, but describing a minority in a handful of cities. For most American women — and overwhelmingly for rural, poor, immigrant and black women — the decade brought no such freedom. And the reaction was fierce: churches, women's organisations, newspapers and small-town opinion condemned the new behaviour and pushed back against it.

1.7 Prohibition and organised crime

On 17 January 1920 it became illegal to make, sell or transport alcohol anywhere in the United States; fourteen years later the ban was repealed. It was not imposed on an unwilling country: temperance campaigners — the Anti-Saloon League and the Woman's Christian Temperance Union — had been winning state bans for decades, and their arguments carried real weight: alcohol was genuinely implicated in domestic violence, industrial accidents, poverty and saloon corruption. Wartime added that grain should feed soldiers and that brewing was a German industry. The 18th Amendment was ratified in January 1919 and the Volstead Act defined the ban.

Enforcement failed almost immediately, for reasons built into the law. The Amendment banned production, sale and transport but not consumption or possession — drinking itself was never a crime. The federal Prohibition Bureau began with about 1,500 agents for a population of 120 million, two long land borders and thousands of miles of coastline; agents were poorly paid and easily bribed. And the ban was wildly unpopular in exactly the places hardest to police — big cities with large immigrant populations for whom wine and beer were ordinary life. The supply continued illegally, and because it was illegal it was enormously profitable and available only to people prepared to use violence: bootleggers smuggled spirits from Canada and the Caribbean; “moonshine” was distilled at unpredictable and sometimes poisonous strength; speakeasies multiplied — estimates for New York City alone run from 20,000 upwards. The gangs that won control — most famously Al Capone's Chicago organisation, with an estimated income of $60 million a year by 1927 — bought police, officials, judges and politicians. The St Valentine's Day Massacre (14 February 1929), seven men machine-gunned in a garage, made gang warfare national news. By the early 1930s the case for repeal had assembled itself: the law was openly flouted, it had created a criminal industry, and — decisively, once the Depression arrived — the legal drinks trade meant jobs and tax revenue. The 21st Amendment repealed Prohibition in December 1933.

1.8 Race and immigration

Two population movements set the context. The Great Migration brought roughly 1.5 million African-Americans from the rural South to Northern cities between 1916 and 1930 — drawn by wartime industrial jobs, pushed by sharecropping debt, lynching and disfranchisement. They found work but also segregated housing, exclusion from most unions, and white resentment that turned violent: there were serious race riots in Northern cities, and black newcomers were frequently used as strike-breakers, deepening the antagonism. Meanwhile European immigration — over a million a year before the war — resumed in 1919–20, now predominantly from southern and eastern Europe: Italians, Poles, Russians, Greeks, and large numbers of Jews and Catholics. The reaction combined economic anxiety (jobs, housing), cultural anxiety (the era's widely believed pseudo-science claimed the “new” immigrants could not be assimilated), religious hostility to Catholics and Jews, and political fear — the Russian Revolution had made radicalism seem an imported infection (see 1.9).

Congress acted decisively. The Emergency Quota Act (1921) limited annual immigration from each country to 3% of its nationals in the 1910 census. The National Origins Act (1924) cut this to 2% — and moved the base year back to 1890, before the great southern and eastern European wave, so the quotas were deliberately weighted towards Britain, Ireland and Germany; Asian immigration was almost entirely barred. From 1929 a ceiling of around 150,000 a year applied. This ended a century of largely open immigration. Outside the law, the Ku Klux Klan — revived 1915 — provided the organised expression of the same feelings, reaching perhaps 4–5 million members at its mid-1920s peak, and not confined to the South: Indiana, Ohio and Oregon were strongholds. Its targets were African-Americans but also Catholics, Jews, immigrants, bootleggers and anyone judged to violate small-town morality; its methods ran from parades and boycotts to floggings, arson and murder; its members included sheriffs, judges and elected officials, which is why prosecutions were rare. Its collapse was rapid and self-inflicted: the 1925 conviction of Indiana Grand Dragon David Stephenson for a sexual assault leading to a woman's death destroyed the Klan's claim to moral authority, and membership collapsed within a few years.

1.9 The Red Scare and Sacco and Vanzetti

The political version of 1.8's anxiety arrived first. The Bolshevik seizure of power in 1917 convinced many Americans that revolution was exportable, and conditions at home seemed to confirm it: the largest strike wave in American history to that date in 1919 (including a general strike in Seattle and a police strike in Boston), two new American communist parties, and a series of letter bombs — one damaging the Attorney General's own house. A. Mitchell Palmer responded with mass arrests of suspected radicals in late 1919 and January 1920 — the Palmer Raids: several thousand seized, often without warrants and frequently on no evidence beyond membership of an organisation or possession of foreign-language literature; several hundred foreign-born radicals deported. The scare subsided during 1920 — the predicted revolution never came, and the methods began to attract legal criticism.

Its most lasting product was a criminal case. In May 1920 Nicola Sacco and Bartolomeo Vanzetti — Italian immigrants and self-declared anarchists — were arrested for a payroll robbery and double murder in Massachusetts. They were convicted in July 1921 in a trial in which the prosecution and the judge dwelt on their politics, their draft evasion and their nationality; the physical evidence was contested and the ballistics disputed. Appeals ran for six years; a confession by another man was rejected; a governor's commission upheld the verdicts; and the two were executed on 23 August 1927 — by which point the case had produced demonstrations in Europe and South America as well as across the United States.

Chapter 2 — Bust, New Deal and war, 1929–1945

Sixteen years in which America fell further than any industrial economy had ever fallen, then rose higher than any had ever risen. Two arguments run through the chapter. The first concerns experience: the Depression was not one event but many different ones, depending on who and where you were. The second concerns explanation: how much of the recovery was the New Deal's achievement, and how much the war's? That second question is the most frequently examined judgement in this option.

2.1 The Depression as lived experience

The crash was concentrated in a fortnight. Prices had been sliding since September; on Black Thursday (24 October 1929) nearly thirteen million shares changed hands, and on Black Tuesday (29 October) over sixteen million, in free fall. Because so much buying had been on the margin (1.4), brokers demanded immediate repayment, forcing more selling. By July 1932 the Dow had fallen from 381 to about 41. The banking system turned this into general catastrophe: banks had lent to speculators and invested in shares themselves; as loans went bad, depositors queued to withdraw savings; because banks hold only a fraction of deposits in cash, the queues themselves destroyed solvent institutions. Around 9,000 banks failed between 1930 and 1933, and their depositors — most of whom had never bought a share — lost everything, because deposits were not insured. With savings gone, consumers stopped buying; factories cut production, then workers; each round of unemployment reduced demand further. GNP fell from roughly $103 billion (1929) to about $56 billion (1933); unemployment rose from about 1.6 million to an estimated 12–13 million — roughly a quarter of the workforce. (Federal unemployment statistics were not systematically collected before 1940, so all Depression totals are estimates — give them as ranges.)

The human results differed sharply by group:

• Industrial workers faced unemployment with no system to catch them: relief was local and charitable, and the cities with the most unemployed ran out of funds first. Shanty settlements — sardonically called Hoovervilles — appeared on the edges of cities; hundreds of thousands took to the roads and freight trains.
• Farmers, already depressed through the 1920s (1.3), saw prices fall by roughly half again — crops were burned rather than sold at a loss; foreclosures rose steeply; and in parts of the Great Plains drought and years of unsuitable ploughing produced the Dust Bowl, driving the “Okies” west towards California.
• Businessmen and the middle class: small firms failed in enormous numbers, and the assumption that thrift and effort guaranteed security was destroyed — one reason the psychological impact ran so deep.
• African-Americans and other minorities were laid off first and given relief last; black unemployment ran at roughly double the national rate.

2.2 Hoover, Roosevelt and the election of 1932

Hoover was not idle — separate what he did from what he was believed to have done. His guiding belief was rugged individualism: self-reliance and voluntary cooperation, with direct federal relief rejected as corrosive of both. He secured business pledges to maintain wages, raised public-works spending (including the dam that bears his name), tried to support farm prices, and in 1932 created the Reconstruction Finance Corporation to lend to banks and businesses, followed by the first federal loans to states for relief. Measured against previous presidencies this was substantial. But two decisions made things worse — the Hawley–Smoot Tariff (1930) raised duties to record levels and other countries retaliated, contracting world trade; and his insistence on a balanced budget produced a tax rise in 1932, exactly when demand needed support. What destroyed him was the impression he gave: reassurances that prosperity was around the corner as the queues lengthened; resistance to direct relief until 1932; and in July 1932 the Bonus Army — around 20,000 unemployed First World War veterans camped in Washington for early payment of a promised bonus — cleared by troops under General MacArthur, with tear gas and burning shanties on the newsreels. “Hooverville” was already a word; that fortnight fixed it.

Roosevelt offered almost the opposite in temperament: Governor of New York, wealthy, disabled by polio since 1921 (a fact largely concealed), he campaigned energetically across the country — itself a contrast — promising a “new deal for the American people” and, crucially, promising action without specifying much of it. He won 472 electoral votes to Hoover's 59, with about 57% of the popular vote, and the Democrats took both houses. Between election and inauguration (4 March 1933), the banking crisis reached its worst point.

2.3 What the New Deal did

The New Deal was not a single plan but a stream of programmes, and the way to remember it is by aim rather than by alphabet — Roosevelt's own formulation: relief, recovery, reform. The Hundred Days (March–June 1933) were extraordinary: Roosevelt closed every bank and reopened only those inspected and declared sound, explaining the decision in the first of his fireside chats (12 March 1933) — informal radio broadcasts that made the presidency audible in the home. Congress then passed measure after measure.

Effectiveness varied enormously by group — which is what the specification actually asks:

• Industrial workers gained most: union rights under the Wagner Act, better wages and hours. Homeowners and depositors were genuinely protected.
• Farmers who owned land benefited from higher prices — but tenants and sharecroppers, many of them black, were often evicted when landlords took acres out of production: a programme designed to help agriculture damaged the poorest people in it.
• African-Americans received relief and jobs, and a “Black Cabinet” of advisers had real influence — yet the CCC ran segregated camps, agricultural and domestic workers were excluded from Social Security (removing the majority of black workers from its protection), and Roosevelt never backed a federal anti-lynching law, for fear of losing the Southern Democrats whose votes he needed.
• Women gained the first female Cabinet member (Frances Perkins) and benefited from relief — but NRA codes frequently set lower minimum wages for women's work, and married women were often barred from federal jobs where a husband was employed.
• Native Americans gained a measure of self-government and religious freedom under the 1934 Indian Reorganization Act.
• Unemployment fell but never disappeared: from about 12–13 million (1933) to roughly 9–10 million in 1939.

2.4 Opposition, the Supreme Court and the President

From the right, business leaders and Republicans objected that the New Deal raised taxes, ran deficits, favoured unions and stretched the Constitution; the American Liberty League (1934), funded by wealthy businessmen, campaigned against it, and some critics called Roosevelt a dictator or a traitor to his class. From the courts came the most serious challenge — one Roosevelt could not out-argue. The Supreme Court struck down the NRA in Schechter (May 1935) and the AAA's processing tax in Butler (January 1936); with more cases pending, the whole programme was in doubt. Roosevelt's response — the court-packing plan of February 1937, proposing up to six additional justices — failed badly in Congress and damaged him with his own party. The irony: the Court then shifted anyway, upholding the Wagner and Social Security Acts, and retirements soon let him appoint justices by the normal route.

From the left came the charge that the New Deal protected capitalism rather than reforming it. Huey Long's “Share Our Wealth” proposed confiscatory taxation of large fortunes and a guaranteed family income — a formidable national following before his assassination in September 1935. Father Coughlin's radio broadcasts, reaching millions, moved from support to bitter opposition (and later into antisemitism). Dr Francis Townsend campaigned for generous old-age pensions. None won power — but the Second New Deal of 1935, with Social Security and the Wagner Act, was in part a response to the pressure they generated. Roosevelt's own contribution is separable from his programme's: the fireside chats created a direct relationship between president and public no predecessor had attempted; he experimented, abandoned what failed, and hired economists and academics (the “Brains Trust”); his declaration that the only thing to fear was fear itself was not merely rhetoric, since bank runs were driven by panic; his four election victories — including the 1936 landslide, 523 electoral votes to 8 — gave him authority; and Eleanor Roosevelt extended his reach into questions he could not politically raise himself, particularly the position of black Americans.

2.5 Culture in hard times

The entertainment industries did not collapse with everything else. Cinema attendance dipped early, then recovered to 1920s levels or higher by the late 1930s — and what people wanted was largely escape: Astaire–Rogers musicals, screwball comedies, gangster films, Disney, and the great spectacles of 1939 (Gone with the Wind, The Wizard of Oz). Radio was cheaper still: comedy, serials, soap operas (sponsored by soap manufacturers), and swing from the big bands of Benny Goodman, Count Basie and Duke Ellington. Joe Louis's 1938 defeat of Max Schmeling carried unmistakable political meaning. Not all of it was escapist: Steinbeck's The Grapes of Wrath (1939) turned the Dust Bowl migration into a national argument about justice; the WPA arts projects paid photographers to record rural poverty, painters to decorate public buildings, and writers to interview surviving former slaves; and Farm Security Administration photography produced the images by which the Depression is still remembered.

2.6 War and the end of the Depression

Between 1939 and 1945 American output roughly doubled and unemployment effectively disappeared. Policy moved in stages: the Neutrality Acts were relaxed from 1939 to permit “cash and carry” munitions sales to Britain and France; the Lend-Lease Act (March 1941) let the president supply war material — around $50 billion over the war — to nations whose defence he judged vital, without immediate payment, putting American factories to work on a vast scale before a single American soldier was engaged; Pearl Harbor (7 December 1941) brought full mobilisation.

The economic mechanism is the heart of the argument about the New Deal, so state it plainly: government placed orders on an unprecedented scale and paid by borrowing, so demand was no longer limited by what consumers could afford. Federal spending rose to levels the New Deal had never approached. Factories converted from cars to aircraft and tanks; shipyards launched merchant vessels in weeks; new industries appeared in the South and West. Roughly 17 million new civilian jobs were created; with 16 million in the armed forces, the labour shortage drew in workers previously excluded (2.7). Unemployment fell from 9–10 million (1939) to about 1 million (1944). By 1945 the United States held most of the world's monetary gold and produced roughly half of global manufacturing output. At home, wages rose and overtime was plentiful; rationing limited what could be bought, so households accumulated the savings that would fuel the post-war boom (3.1); war bonds sold on a mass scale; and taxation was extended to most wage-earners for the first time, through payroll deduction.

2.7 War and social change

The war moved millions of people into new places and new jobs — and exposed a contradiction that would define the next twenty years: a country fighting racism abroad while practising segregation at home. This section is the origin point for Chapter 3.

• African-Americans — opportunity and insult at once. Around a million served, but in segregated units, largely in support roles, often trained in the South under Jim Crow (the Tuskegee airmen won distinction against official resistance). At home, war industries initially refused to hire black workers — until A. Philip Randolph threatened a march on Washington in 1941 and Roosevelt issued Executive Order 8802 (June 1941), banning discrimination in defence industries and creating the Fair Employment Practices Committee — limited powers, but a new principle. The second Great Migration carried well over a million African-Americans to Northern and West Coast industrial cities; competition for scarce housing produced serious violence, worst in Detroit, June 1943 (around 34 deaths). The Pittsburgh Courier's Double V campaign — victory abroad and victory at home — named the contradiction explicitly, and NAACP membership grew roughly tenfold during the war.
• Women entered the workforce in unprecedented numbers — including engineering, shipbuilding and aircraft assembly. Women in paid work rose by around 6 million; “Rosie the Riveter” became the government's image of patriotic female labour; around 350,000 served in the armed forces; federal childcare appeared, on a limited scale, for the first time. But the terms were explicitly temporary: women were usually paid less than the men they replaced, and at the war's end they were expected to leave — and largely did, whether or not they wished to. The proportion of married women in work nevertheless remained higher after 1945 than before.
• Japanese-Americans experienced the war as the removal of their rights: after Executive Order 9066 (February 1942), around 110,000–120,000 people of Japanese descent — the majority American citizens — were removed from the West Coast to inland internment camps, losing homes, businesses and possessions. No comparable action was taken against Americans of German or Italian descent.

Chapter 3 — Post-war America, 1945–1973

America emerged from the war as the richest and most powerful nation on earth, and for a quarter of a century most white Americans grew steadily better off. This chapter explains that prosperity and then follows the three great challenges to it: the accusation that affluence had been bought at the cost of political freedom, the campaign to extend it to black Americans, and the argument that it had left both the poor and women behind.

3.1 Affluence and its causes

Between 1945 and the late 1960s American living standards rose faster and for more people than at any time before or since. The causes combined: wartime accumulated savings and pent-up demand released as production converted back (2.6); the GI Bill (1944) — subsidised university education, vocational training, unemployment pay and cheap guaranteed mortgages for around 16 million veterans, the mechanism by which millions of working-class families entered the middle class and became homeowners; permanent government spending — the Cold War sustained high defence expenditure, supporting aircraft, electronics and aerospace and reshaping California, Texas and the South; the baby boom (births peaked in the late 1950s at over 4 million a year), guaranteeing decades of demand; expanding credit, with the first credit cards in the 1950s; and almost no industrial competition — Europe and Japan were devastated, so American manufacturers sold into world markets they effectively owned.

The most visible result was suburbanisation: federal mortgage guarantees, cheap land, mass-production building and the new highways made it possible to build entire towns at speed — Levittown (begun 1947) the model; roughly 13 million new homes were built in the decade after 1948, overwhelmingly in suburbs. Car ownership rose from around 40 million vehicles (1950) to some 60 million (1960); the Interstate Highway Act (1956) committed the federal government to a national motorway network. The American Dream — that any American could achieve prosperity through effort — looked, for suburban families, like a description of reality. But it was never universal: Michael Harrington's The Other America (1962) documented what the statistics obscured — something like 40–50 million Americans in poverty, concentrated among the elderly, the rural South and Appalachia, black and Hispanic city-dwellers, and single-parent families. And suburbanisation itself sharpened the divide: federal mortgage guarantees were routinely denied in black neighbourhoods, and covenants and lending practices kept the new suburbs white — the flagship programme of post-war opportunity actively deepened residential segregation.

3.2 McCarthyism

At the height of its prosperity, the United States conducted a search for internal enemies that ruined careers and narrowed the limits of acceptable opinion. The fear was not baseless: between 1945 and 1950 the USSR installed communist governments across eastern Europe, China's revolution succeeded, the Soviets tested an atomic bomb, and there were genuine cases of Soviet espionage. Against that background: Truman's federal loyalty programme (1947); HUAC's Hollywood hearings, jailing and blacklisting the Hollywood Ten (the informal blacklist eventually covered hundreds in film, radio and television); Alger Hiss convicted of perjury (1950); the Rosenbergs executed (1953) for passing atomic secrets — a case still argued over, particularly Ethel's role.

Senator Joseph McCarthy gave the phenomenon his name. At Wheeling, February 1950, he claimed to hold a list of communists in the State Department — never substantiated, the numbers changing between tellings, but politically explosive and amplified by the press. For four years he accused officials, diplomats, academics and eventually the army, in hearings where the accused had few protections and refusal to answer was presented as proof of guilt. His method — sweeping charges, shifting evidence, guilt by association — became a general licence, and thousands lost jobs in government, education, unions and entertainment. His fall was quick once his target could fight back: the televised Army–McCarthy hearings (1954) let a national audience watch him bully witnesses across 36 days; Edward R. Murrow had already dismantled his methods on air; the Senate censured him in December 1954, and his influence ended.

3.3 Teenagers, television and rock and roll

Television spread with astonishing speed — from under 10% of homes (1950) to around 87% (1960) — reorganising domestic life around three national networks (NBC, CBS, ABC) and making advertising more powerful than radio ever had. Its political consequences recur through this chapter: the Army–McCarthy hearings (3.2), the 1960 Kennedy–Nixon debates (watched by an estimated 70 million, where appearance mattered as much as argument), and above all the transmission of civil rights confrontations into Northern living rooms (3.5). Its content, meanwhile, was strikingly narrow: family sitcoms presenting a suburban, white, male-breadwinner ideal that matched the advertisements between them.

The teenager was partly a marketing category: rising family incomes and part-time work gave adolescents disposable money (estimated in the billions annually by the late 1950s); longer high-school education kept them together in age-segregated institutions; cars gave them privacy. Industries formed to serve them — records, radio stations, films, clothing, drive-ins. Rock and roll was the music that resulted, and its origins are the reason it alarmed adults: it emerged from black rhythm and blues, and its arrival in the white mainstream — Elvis Presley from 1956, with Chuck Berry, Little Richard and Bill Haley — meant white teenagers dancing to music made by black musicians at exactly the moment segregation was being challenged in the courts. Objections were framed as morality and delinquency, but the racial anxiety was explicit in much of the criticism, and some stations and city authorities banned the music outright. Alongside it, Rebel Without a Cause (1955) and the Beat writers offered images of youthful alienation from suburban respectability.

3.4 The structure of segregation

Before you can explain the civil rights movement you must understand precisely what it was fighting — a system more elaborate than a set of unfriendly attitudes. The legal foundation was Plessy v Ferguson (1896): “separate but equal” facilities were constitutional. On that basis Southern states built Jim Crow — statutes requiring separation in schools, buses, trains, waiting rooms, parks, hospitals, restaurants, cinemas, drinking fountains and lavatories. The facilities were separate and systematically unequal: spending per white pupil was commonly several times that per black pupil. Political exclusion made the system self-sustaining: despite the 15th Amendment, Southern states used literacy tests administered at the registrar's discretion, poll taxes, grandfather clauses and intimidation — in Mississippi in 1964, fewer than 7% of black adults were registered. Because they could not vote, they could not remove the officials who enforced the system or serve on the juries that tried those who attacked them. Violence completed the structure: the murder of fourteen-year-old Emmett Till in Mississippi in August 1955, and the acquittal of his killers by an all-white jury, demonstrated the whole mechanism working at once. The North had no Jim Crow laws but had de facto segregation produced by housing — discriminatory lending, restrictive covenants and the federal mortgage practices of 3.1 — which segregated schools by catchment area and confined employment. Northern segregation was harder to attack because there was no statute to strike down.

The first major breach came through the courts — because the NAACP had spent twenty years building towards it. In Brown v Board of Education (17 May 1954) the Supreme Court ruled unanimously that segregated schooling was inherently unequal and therefore unconstitutional, overturning Plessy. It was a landmark — and it was resisted. The follow-up ruling asked only for desegregation “with all deliberate speed”; Southern states responded with delay, school closures, and a Southern Manifesto signed by over 100 members of Congress (1956). At Little Rock (September 1957), Governor Orval Faubus used the Arkansas National Guard to block nine black students from Central High School; Eisenhower — reluctantly, on the constitutional principle rather than the moral one — sent federal troops to escort them. Even so, by the early 1960s only a tiny percentage of Southern black children attended desegregated schools.

3.5 Non-violent protest

Between 1955 and 1965 a mass movement achieved what litigation alone had not — and the campaigns were not simply expressions of anger but a deliberate method of forcing federal intervention. The Montgomery bus boycott established the pattern: when Rosa Parks, an experienced NAACP activist, was arrested in December 1955 for refusing to give up her seat, the city's black population — roughly 75% of bus passengers — stopped using the buses for over a year, organising car pools and walking to work. The company lost most of its revenue, and in 1956 the courts ruled bus segregation unconstitutional. Three lessons: economic pressure worked; black communities could sustain collective action; and the campaign produced a national spokesman in the twenty-six-year-old Martin Luther King Jr, whose Christian and Gandhian case for non-violence gave the movement a language Northern white opinion found difficult to reject.

King founded the SCLC (1957) to coordinate church-based campaigns. Students broadened the movement: the Greensboro sit-in (February 1960) — four college students at a segregated lunch counter — was copied across the South within weeks, and SNCC was formed to organise it. The Freedom Rides (May 1961) tested a court ruling against segregation on interstate buses; riders were beaten and a bus burned in Alabama, and the publicity forced the Kennedy administration to act. Birmingham (April–May 1963) shows the strategy at its most explicit: King chose Alabama's most segregated city precisely because its police commissioner, Eugene “Bull” Connor, was likely to respond with force. Marches — including by schoolchildren — provoked mass arrests, dogs and fire hoses, all photographed and filmed; the images ran worldwide; Kennedy declared civil rights a moral issue and introduced a civil rights bill. The March on Washington (28 August 1963) brought around 250,000 people to the capital and King's “I have a dream” speech to a national television audience. Selma (March 1965), where marchers demanding voting rights were attacked on a bridge in front of cameras, produced the Voting Rights Act within five months. (Freedom Summer, 1964 — the Mississippi voter-registration drive in which three activists were murdered — sits between them.)

3.6 The other tradition: Malcolm X and Black Power

From the mid-1960s the movement divided — because Northern black Americans faced a different problem from Southern ones, and non-violence had been designed for the Southern version. In Northern and Western cities there were no segregation statutes to repeal. The problems were poverty, unemployment at roughly double the white rate, decaying housing produced by the practices of 3.1, poor schools and hostile policing — none removable by a court ruling, and the legislation of 1964–65 (3.7) barely touched them. In August 1965, five days after the Voting Rights Act was signed, the Watts district of Los Angeles erupted in six days of rioting that left around 34 dead — a sequence suggesting that legal equality and lived conditions had come apart.

Malcolm X articulated the alternative analysis: rejecting integration as a goal, he argued black Americans should build their own institutions, take pride in their African heritage, and defend themselves rather than submit — “by any means necessary”. He was scathing about the March on Washington and the assumption that white America could be appealed to morally. After breaking with the Nation of Islam in 1964 and visiting Mecca and Africa he moved towards a broader anti-racist position — but he was assassinated on 21 February 1965, and it was his earlier, sharper arguments that shaped what followed. Black Power emerged as a slogan in 1966, adopted by SNCC under Stokely Carmichael, which expelled its white members and abandoned non-violence as a principle. The Black Panther Party (October 1966) combined armed patrols monitoring police behaviour with free breakfast programmes, clinics and legal aid — a mixture that made it genuinely popular locally and a target for federal surveillance and violent confrontation. Cultural nationalism spread wider still — dress, hair, music, the reclaiming of African history — and reached a global audience when two American athletes raised gloved fists at the 1968 Olympics. The movement's most prominent leaders were both dead by 1968: Malcolm X in 1965, and King — by then campaigning on Northern poverty and against the Vietnam War — assassinated in Memphis on 4 April 1968, followed by rioting in over a hundred cities.

3.7 Federal action: the Civil Rights Acts

3.8 Kennedy, Johnson and the Great Society

Kennedy's New Frontier promised more than it delivered: he raised the minimum wage, extended social security, funded some urban housing, and set up the Peace Corps and a Commission on the Status of Women — but a conservative coalition of Republicans and Southern Democrats blocked his proposals on health insurance, federal aid to education and civil rights. His assassination in November 1963 changed the political arithmetic: Johnson, a formidable legislative operator, used the shock and his own 1964 landslide (about 61% of the popular vote) to pass a programme stalled for a decade.

• The War on Poverty (declared 1964). The Economic Opportunity Act (August 1964) created the Office of Economic Opportunity: Job Corps training for unemployed young people, VISTA volunteers, Community Action Programs run partly by the poor themselves, and Head Start — pre-school education for poor children, still in existence. Food stamps were expanded; rent supplements and urban development funds followed.
• Education. The Elementary and Secondary Education Act (1965) broke a long deadlock by directing federal money to schools according to the number of poor children they taught; the Higher Education Act (1965) created federal scholarships and loans.
• Health. 1965 produced the two largest additions to American social provision since 1935: Medicare (hospital and medical insurance for the over-65s) and Medicaid (healthcare for those on low incomes). Both survived, and both remain politically contested.

The results were real and partial. The proportion of Americans below the federal poverty line fell from around 22% (1959) to roughly 12% (1969) — the sharpest fall in modern American history, and the strongest single piece of evidence for the programme; elderly poverty fell furthest, largely because of Medicare and social security increases. But the programme was overtaken by three problems: the cost of the Vietnam War, which consumed the funds and political attention domestic reform required; the administrative difficulty of Community Action Programs, which produced conflict with city governments; and a political backlash, as riots and rising crime let opponents argue federal money had made matters worse. Johnson chose not to seek re-election in 1968.

3.9 The women's movement

The unit's last section returns to the question first raised in 1.6 — how far the position of American women had actually changed. The post-war decades had pushed strongly towards domesticity: wartime jobs ended (2.7), suburban life was organised around the male breadwinner, and advertising and television presented homemaking as fulfilment. Yet the number of married women in paid work kept rising through the 1950s, largely out of economic necessity — and the gap between that reality and the official ideal was widening. Betty Friedan's The Feminine Mystique (February 1963) named the discontent: based on surveys of college-educated suburban women, it argued the domestic ideal was producing frustration and waste on a large scale, and it sold in enormous numbers. The same year, the Presidential Commission on the Status of Women reported on discrimination, and Congress passed the Equal Pay Act (June 1963). Then in 1964 Title VII of the Civil Rights Act (3.7) prohibited employment discrimination on grounds of sex — a legal weapon campaigners had not expected to have. Because the new EEOC was slow to take sex discrimination seriously, Friedan and others founded NOW (June 1966), explicitly modelled on civil rights organisations, campaigning on hiring, promotion, segregated job advertisements, childcare and legal reform; a younger women's liberation movement developed alongside it, using consciousness-raising groups and direct action.

The legal gains were considerable. Reed v Reed (1971) — the first Supreme Court ruling striking down a law for sex discrimination under the Fourteenth Amendment. Title IX (1972) barred sex discrimination in federally funded education, transforming women's access to graduate programmes and to sport. Congress passed the Equal Rights Amendment (22 March 1972), which would have written sex equality into the Constitution. And Roe v Wade (22 January 1973) held that the constitutional right to privacy protected a woman's decision to end a pregnancy. Then the movement met organised opposition. The ERA needed 38 states and initially moved quickly; Phyllis Schlafly's STOP ERA (1972) mobilised conservative and religious women with the argument that the Amendment would remove protections women valued — exemption from conscription, alimony, single-sex facilities — and would attack the family. Ratification stalled at 35 states and the Amendment failed. Roe similarly energised a counter-movement that has shaped American politics ever since. And the economic gap closed slowly: women's median earnings remained around 60% of men's through the early 1970s, with occupational segregation into lower-paid work persisting.
