The document summarizes several key aspects of life in the United States during the 1920s. Three trends dominated this period: renewed isolationism, the resurgence of nativism, and political conservatism. President Harding encouraged a return to "normalcy" but his administration was plagued by scandals. Communism was seen as a threat, leading to raids targeting suspected communists. Business boomed, especially in the automobile industry, and new technologies like radio and movies shaped mass culture. Prohibition was also enacted but widely resisted, leading to the growth of organized crime.
