In 2024, 31% of Americans belong to the upper middle class, a significant increase from just 10% in 1979. This income bracket is defined for families of three earning between $133,000 and $400,000 annually. The demographic primarily consists of white-collar professionals, such as accountants, engineers, and corporate managers, rather than tech entrepreneurs. Interestingly, many individuals in this category, like Randy Shilling, a 58-year-old chemical plant worker from Texas who has saved over $3 million for retirement, often see themselves as average citizens. Research from the American Enterprise Institute indicates that the growth of the upper middle class is largely due to wages increasing faster than prices over time, particularly for those with college degrees. This trend highlights a shift in the economic landscape, where a broader segment of the population is experiencing upward mobility.
