The economic sector most responsible for the prosperity of the 1920s was not agriculture, but rather industries such as manufacturing, factories, shipyards, and transportation systems in urban areas.
Agriculture actually suffered the most during this time, as overproduction led to a decrease in prices and caused many farmers to struggle. Attempts by Congress for federal price supports were consistently vetoed by President Coolidge, further worsening the situation for farmers.
