How did the outbreak of World War 2 effect the economy in the US?

The outbreak of World War II significantly boosted the U.S. economy, as it shifted focus toward war production and increased government spending. Factories transitioned from consumer goods to military supplies, creating millions of jobs and reducing unemployment. This mobilization also led to technological advancements and infrastructure improvements. Ultimately, the war effort helped lift the U.S. out of the Great Depression and positioned it as a global economic leader post-war.
