What problem arising from US industrialization did the progressive reformers of the late 19th and early 20th centuries want the federal government to address?

Progressive reformers sought to address the significant social and economic inequalities that arose from rapid industrialization in the U.S., such as labor exploitation, unsafe working conditions, and the monopolistic practices of large corporations. They aimed for the federal government to implement regulations that would protect workers' rights, improve public health and safety, and ensure fair competition in the marketplace. Additionally, reformers pushed for social justice initiatives to address issues like poverty, education, and women's suffrage, advocating for a more equitable society.
