Big business was regarded by the Harding, Coolidge, and Hoover administrations as America's most important strength.
Indeed, historians have a name that identifies these presidential periods: Prosperity and thrift: the Coolidge Era. This period of 1920 to 1933, was a tumultuous period in which the United States passed from a time of economic prosperity during the "Roaring 1920s" due to mass consumption that was based on credit to the terrible economic years of the Great Depression.
