What would be the best(or most effective) economic theory to use for a research/ argumentative essay on the economic benefits of child labor in the USA from the late1800s to the early1900s..Feel free to include a cite of a scholarly article on the topic dicussing the economic benefits of child labor. I know this is a pretty broad question (not expecting much need a point in the right direction) to start the paper. maybe even a topic sentence or purpose statement I can use to mold my essay
