World War II had a profound impact on the economies of Western nations, leading to rapid industrial growth and economic recovery from the Great Depression. The war necessitated mass production of goods, which stimulated economies, increased employment, and expanded technological advancements. Post-war, many Western nations experienced a significant economic boom, often referred to as the "Golden Age of Capitalism." Governments also implemented policies to promote consumer spending and welfare, further solidifying middle-class prosperity. This economic transformation laid the groundwork for modern welfare states and contributed to overall global economic stability in the following decades.
