Why was the lowell mill system so revolutionary

The Lowell mills were the first hint of the industrial revolution to come in the United States, and with their success came two different views of the factories. For many of the mill girls, employment brought a sense of freedom. Unlike most young women of that era, they were free from parental authority, were able to earn their own money, and had broader educational opportunities. Many observers saw this challenge to the traditional roles of women as a threat to the American way of life. Others criticized the entire wage-labor factory system as a form of slavery and actively condemned and campaigned against the harsh working conditions and long hours and the increasing divisions between workers and factory owners.
