World War 1 had many devastating effects on the economy of the United States before, during, and after the war. Before the war and right up to the war, the United States economy began to experience a boom because people were beginning to have an outburst of jobs due to the fact that the country was preparing for war. During the war, the United States experienced a kind of recession. This was because all of the materials that people could afford to give up were sent to the people fighting for the cause overseas. When solders came home, thre was another economic downturn because the country became in debt from war expenses, and there were more people than jobs within the nation at that time.
