Yet, the United States enjoyed a period of prosperity. Many families purchased their first automobile, radio and refrigerator. They went to the movies. Women finally won the right to vote in 1920. In October 1929 the good times ended with the collapse of the stock market and an economic depression. Businesses and factories shut down. Banks failed. Farms suffered. By November 1932, 20% of Americans did not have jobs. That year the candidates for president debated over how to reverse the Great Depression. Herbert Hoover, the president during the collapse, lost to Franklin Roosevelt.
