Cross-Topic Links
- → Topic 14 (New Deal Success): WW2 accomplished what the New Deal could not — unemployment fell from 14% to 1.2% as war production created 17 million jobs, making this the strongest argument against judging the New Deal a full economic success.
- → Topic 16 (Segregation): The Double V Campaign (victory abroad + victory at home) shows how WW2 directly energised the civil rights movement — 1 million Black Americans who fought fascism returned expecting equality, fuelling the NAACP's growth from 50,000 to 500,000 members.
- → Topic 9 (Intolerance): McCarthyism (1950-54) was a direct continuation of the 1920s Red Scare — both exploited fear of communism and used accusations without evidence; the same WASP anxieties about "outsiders" appeared in a Cold War context.
- → Topic 4 (Economic Boom): The post-war consumer boom (cars, television, suburbs) repeated and expanded the 1920s pattern — the same combination of mass production, credit, and advertising drove prosperity, but this time on a far larger scale and with lasting middle-class stability.
- → Topic 17 (Direct Action): The post-war prosperity and the Cold War context both shaped the Civil Rights movement — America's claim to defend freedom abroad made segregation at home a diplomatic liability, giving activists extra leverage on federal politicians.
