Which best explains why the industrial revolution led to a larger middle class?

The Industrial Revolution made drastic changes in the lives of individuals. Two classes that benefited from it were the middle and upper classes. Even though most could afford goods anyway, the prices lowered even more, so that those who could not afford them before could now enjoy the comfort and convenience of the new products being made.

The middle class was composed of businessmen and other professionals. The larger the Industrial Revolution grew, the more powerful these individuals became. Individuals and groups formed new libraries, schools, and universities because there was a sudden need for education (possibly due to the increase in population). The middle and upper classes had better food and housing, which led to fewer diseases and longer living among these groups. Since these classes were treated so well, their population grew and thus had minimal difficulty living during the Industrial Revolution.
