How did world war ii affect the economy of the US?

World War II significantly boosted the U.S. economy by ending the Great Depression, as massive military spending led to increased production and job creation. Industries shifted to wartime production, resulting in technological advancements and a workforce expansion, including the entry of women and minorities into the labor market. Post-war, the economy transitioned to consumer goods, leading to a period of prosperity and growth in the middle class, while also establishing the U.S. as a dominant global economic power.
