What is one reason that progressives tried to eliminate child labor in the US?

One reason that progressives tried to eliminate child labor in the US was to protect the well-being and rights of children. They believed that child labor violated the principles of human rights and hindered children's physical, mental, and social development. Progressives argued that children deserved to receive an education, have time to play and grow, and be protected from dangerous and exploitative working conditions. By advocating for the elimination of child labor, progressives sought to ensure that children could have a better and healthier future.
