The 1920s became known as the Roaring Twenties due to rising mass consumption in America and breakthroughs in the arts and entertainment industries. Treasury Secretary Andrew Mellon's tax cuts for the rich and Henry Ford's advances in mass production made previously luxury goods more accessible to the middle class. New technologies like the radio and movies provided affordable entertainment. Jazz music and Art Deco became dominant as literary works from Hemingway and Fitzgerald reflected the cultural liberation of the time period. Overall, the economic conditions and developments in arts/entertainment helped define the decade as one of increased spending, innovation, and cultural changes.
