During the 1950s, the incomes of white Americans increased significantly. The post-World War II economic boom led to a period of sustained economic growth, which was accompanied by rising wages and increased job security. This period of economic growth and prosperity is often referred to as the "Golden Age of Capitalism." However, it's important to note that this period of economic growth was not shared equally by all Americans, and many marginalized groups, such as people of color and women, continued to face significant economic and social barriers.
