The Roaring 20s was a time of economic prosperity for the United States. New technology and growing industries advanced the standard of living and pulled the majority of the population to city centers across the country. Reforms for social justice and public health improved the state of cities when new legislation was passed to expand people's rights and advocated for their safety. New technologies also created more leisure time for Americans where they could travel and indulge in entertainment at theaters and at the movies. Modern ideas challenged traditional ones and played a significant role in society. Arts, music, and culture bloomed as people celebrated and partied secretly under Prohibition. While the Roaring 20s certainly roared, the United States still experienced deep-seated racism and hatred towards foreigners and immigrants.
