The Depression caused prices of fish and copper, which were vital to Alaska's economy at the time, to decline. Wages were dropped and the workforce decreased by more than half. In 1935, President Franklin D. Roosevelt thought Americans from agricultural areas could be transferred to Alaska's Matanuska-Susitna Valley for a fresh chance at agricultural self-sustainment. Colonists were largely from northern states, such as Michigan, Wisconsin, and Minnesota under the belief that only those who grew up with climates similar to that of Alaska's could handle settler life there. The United Congo Improvement Association asked the president to settle 400 African-American farmers in Alaska, saying that the territory would offer full political rights, but racial prejudice and the belief that only those from northern states would make suitable colonists caused the proposal to fail.
