The Jungle exposed the terrible situations of the meatpacking industry, brought it to the limelight what was really happening when the government didn't step into businesses. It shadowed a hard working immigrant family and the struggles they faced when coming to America. One of the biggest things it brought to light was the terrible situations seen at a meat packing facility. It also brought up numerous other issues, such as the circumstances employees had to work in, prostitution, and immigration.

This is one of many things that Progressives sought to achieve.
