What are you talking about? You don't seem to have even a basic understanding of this subject. You were fundamentally wrong about needing to outlaw child labor. You didn't seem to know what the Fair Labor Standards Act was until I introduced it to you.
Capitalist are currently working to reintroduce child labor to the US to undercut wages. It's embarrassing for you to respond when you've displayed such a lack of understanding on the topic.
"Every decade following 1870, the number of children in the workforce increased, with the percentage not dropping until the 1920s.[6] Especially in textile mills, children were often hired together with both parents and could be hired for only $2 a week.[7] Their parents could both work in the mill and watch their children at the same time"

Child labor increased during the industrial revolution. You are simply wrong.
