Why does Bagley compare the situation of female factory workers with slavery?

Explanation:

Hi. From the context of your question, we can see that you are referring to Sarah Bagley's article on how female employees were treated during the early days of industrial work. Sarah compared the situation of female employees to slavery. She made this comparison because the women's working hours were very strict and very long, in addition, they received a very small salary. At that time, women worked from 5 am to 7 pm.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
