Final answer:
During the Great Depression, states grew more powerful through increased activism among workers, greater government control of the economy, and expanded governmental power to manage the economy after the United States was attacked.
Step-by-step explanation:
During the Great Depression, states grew more powerful in several ways. First, there was an increased level of activism among workers who believed that the federal government must intervene to help the common citizen. This led to support for the government providing jobs for the unemployed and regulating conflicts between labor and management. Second, the federal government took greater control of the economy to ensure that factories were at peak capacity. Third, the government received almost unlimited power to manage the economy after the United States was attacked in 1941. In hindsight, the same methods used to transform the economy during the war could have ended the Depression sooner.
