US History – 1865 to Present
The expansion of the middle class refers to the growth of a socioeconomic group characterized by a moderate level of income, education, and occupational status, distinct from both the working class and the upper class.

The rise of the middle class played a significant role in shaping American society, influencing cultural norms, political trends, and economic structures.
