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.

Because they had a massive exploration by the mother country (the one responsible by the conquest), which took a considerable part of their goods.

Explanation:

The Latin American colonies were different from the British Colonies (Thirteen Colonies and Canada) because they were explored massively by Portugal and Spain during the three centuries of colonialism. The Iberian countries were following an economic and political idea called Mercantilism which, as the main aspect, was the exploration of a colony, taking the goods and sending it to the mother country. Only a small part was left for the colony. And why those colonies don't rebel against the mother country, you may ask. Because since the very moment the Iberian countries began their colonization, they didn't leave any possibility of revolution, with laws and severe control of the settlers and natives. Any try of revolution or riot was massively dismissed with violence.
