How Far Did US Society Change in the 1920s?

• The Roaring Twenties = a decade of fast economic growth, new technology (cars, radio, cinema) and cultural experimentation (jazz).
• Cars transformed American life — more roads, suburbs, jobs, and freedom of movement — but also concentrated huge power in the hands of businessmen like Henry Ford.
• Radio and cinema created the first truly national, shared culture in US history — everyone, rich or poor, literate or not, could tune in.
• Jazz symbolised the new freedom of the age but was also attacked because of its Black origins and its links to "immoral" nightlife.
• Intolerance ran alongside the boom: WASPs (White Anglo-Saxon Protestants) used new immigration laws and the revived KKK to attack immigrants, Catholics, Jews, and especially Black Americans.
• Jim Crow Laws and lynching kept Black Americans in the South legally and violently oppressed — the NAACP formed to fight back through the courts.
• Prohibition (1920–1933) banned alcohol nationwide, aiming to fix social problems — instead it created organised crime, corruption, and mass law-breaking, so it was repealed.
• Women won the vote (1920) and more entered paid work, giving some — like the "flappers" — real independence. But most women's day-to-day lives barely changed.

What does "Roaring Twenties" actually mean?

Think of the name literally: things were moving so fast that life seemed to "roar" past people. This wasn't just a vibe — it was driven by real economic growth (fuelled by new technology, higher consumer spending, and government policies that favoured business), which raised living standards and created a brand-new "consumer culture" — the idea that you could, and should, buy new goods to enjoy life.

Alongside the economic boom came social experimentation. People — especially young people — started to challenge older, stricter Victorian-era values around behaviour, entertainment, and relationships. Jazz music, radio, and cinema all fed this new spirit.
