Children were often hired in factories during the Industrial Revolution because they could fit into tight spaces between machines and could be paid lower wages than adult workers. Additionally, many children lived in impoverished conditions and needed to work to support their families, making them a cheap source of labor for factory owners. There were also no child labor laws at the time, so factory owners were able to exploit children for their labor without consequences.
