Final answer:
The result of the passing of child labor laws during the Progressive Era was the gradual reduction of child labor, an increase in mandatory school attendance, and a decline in illiteracy rates. Over time, and with considerable advocacy and legislative action, these laws contributed to a significant shift in societal norms, placing greater value on child education and well-being.
Step-by-step explanation:
The passing of child labor laws during the Progressive Era led to significant reforms that transformed American society. Initially, these laws at the state level began reducing the number of children in the workforce, thereby decreasing child fatalities in industrial environments.
In Ohio, legislation limited the number of hours children could work, setting a precedent that, despite falling short of international standards, demonstrated a domestic acknowledgment of the problem. While attempts at federal legislation initially failed and faced opposition from the Supreme Court, the establishment of the U.S. Children's Bureau in 1912 and the eventual ratification of the Fair Labor Standards Act in 1938 signaled the culmination of Progressive efforts to shield children from labor exploitation.
