The document discusses the economic boom of 1920s America. It occurred due to long-term factors like abundant natural resources and a large internal market, as well as short-term factors like the US filling the void left by European industries during World War 1. Key features of the boom included new mass production techniques exemplified by Henry Ford's assembly lines. However, not all groups benefited equally from the prosperity - black Americans, farmers, wage earners and the unemployed struggled despite the overall economic growth.
