What was the main reason for creation of evil service system in the late 1800s

The main reason for the creation of the evil service system in the late 1800s was to provide cheap labor for large industries such as mining, agriculture, and manufacturing. The system relied on indentured servants, convicts, and immigrants who were promised work and better lives in exchange for their labor, but instead were subjected to harsh working conditions, low wages, and little to no freedom. The system was also fueled by racism and discrimination against certain ethnic groups, such as Chinese immigrants and African Americans, who were viewed as inferior and therefore easier to exploit.
