Answer: B. They earned more money than their parents
Explanation:
Child Laborers in the United States was a very widespread practice in the 1800s and early 1900s. These children suffered all manner of abuse and were made to do work that even adults should not do sometimes.
As a result they missed out on school and worked in jobs so dangerous that they risked injury or even death. Some might have made more than their parents if their parents had no job but the money that these children made contributed to the welfare of their family so this was not a negative consequence of child labor.
