Final answer:
The "roaring 20s" ended with the Great Depression, which began with a stock market crash in 1929, leading to widespread economic hardship. This period marked a significant shift in American society and policy, eventually leading to the implementation of Franklin Roosevelt's New Deal.
Step-by-step explanation:
The "roaring 20s" came to an end with the onset of the Great Depression. The decade that was famous for its economic boom, cultural evolution, and technological progress concluded with a devastating stock market crash in 1929, triggering the worst economic downturn in the industrialized world.
The Great Depression led to widespread unemployment, bank failures, and global financial turmoil. The effects of the economic collapse were felt worldwide, affecting both the urban industrial sectors and the rural agricultural communities, exacerbating social and economic issues.
During the 1920s, the United States experienced significant economic growth, but this was accompanied by underlying weaknesses, such as overproduction in agriculture and troubled industries. The exuberant stock market disguised much of the instability until it all came to a screeching halt.
The transition from decadence to depression reshaped American life and would later influence major changes in government policy and the national economy.
The election of Franklin Roosevelt in 1932 brought about "The New Deal," a series of programs aimed at reviving the economy and providing work for the unemployed, including infrastructure projects like the Hoover Dam, and support for the arts through the Federal Writers' Project.
