The Jazz Age of the 1920s saw major cultural and social changes in American society. Young people embraced new styles of dress, music, and greater personal freedom than previous generations. At the same time, religious fundamentalism opposed these changes and sought to preserve traditional values. Economically, lower taxes and new industries like automobiles spurred widespread prosperity, though some groups faced exclusion and hardship. Mass production using assembly lines boosted supplies and reduced costs of goods, fueling a new consumer society.
