A primary reason for the economic success of the U.S. post-World War II was the surge in industrial production and consumer demand fueled by wartime innovation and infrastructure development. The Marshall Plan facilitated the recovery of Europe, creating markets for American goods. The U.S. emerged as a global leader in technology and manufacturing, benefiting from a well-trained workforce and abundant resources. The establishment of international trade systems and organizations, combined with a booming middle class, spurred economic growth. This period also marked the rise of consumer culture, as families spent on goods like automobiles and household appliances, fundamentally transforming American society.
