Some six weeks after the United States formally entered the First World War, the U.S Congress passes the Selective Service Act on May 18, 1917, giving the U.S. president the power to draft soldiers.United States Initially Wilson only had about 100,000 men volunteer for the war. To remedy this situation, Wilson pushed the government to adopt military conscription, which he argued was the most democratic form of enlistment. To that end, Congress passed the Selective Service Act, which Wilson signed into law on May 18, The act required all men in the U.S. between the ages of 21 and 30 to register for military service. Within a few months, some 10 million men across the country had registered in response to the military draft. By the end of World War I in November 1918, some 24 million men had registered under the Selective Service Act. Of the almost 4.8 million Americans who eventually served in the war, some 2.8 million had been drafted.World War I

During WW1 farmers were producing goods which they then exported to European countries who were struggling. They became used to producing large amounts of produce and making high profits. However, when WW1 ended, there was no longer such a large demand for agricultural goods in Europe. The farmers now had a large surplus stock which they were unable to sell abroad. This was partly the fault of the American govt. Having raised taxes on imported goods to prevent Americans buying foreign produce, other countries retaliated by doing the same which left farmers struggling to sell produce within the USA. The end of the war meant that the agricultural industry was declining, and people were unable to make enough money to pay their rent or mortgage. This led to poverty amongst farmers, and therefore they did not participate in the Boom of the 1920s.
