How did the government control the US economy to support the war?

During wartime, the U.S. government implemented various measures to control the economy, including the establishment of the War Production Board (WPB) to prioritize and distribute resources for military production. It also introduced rationing systems to ensure essential goods were available for military use, while curbing civilian consumption. Additionally, the government increased taxes and issued war bonds to finance military expenditures, while promoting war-related industries through incentives and contracts. These strategies collectively aimed to mobilize the economy effectively for war efforts.
