The American middle class refers to a social and economic group in the United States characterized by moderate income levels, stable employment, and access to education. This group typically includes professionals, skilled workers, and small business owners who can afford a comfortable lifestyle, including home ownership and healthcare. Historically, the middle class has been seen as a key driver of the U.S. economy, contributing to consumer spending and economic growth. However, factors such as rising living costs and wage stagnation have raised concerns about the stability and size of the middle class in recent years.
