No, I don't think you understand it fully. That's what the legal minorities and children are for. Ask rural folk over 60 if they had a job as a child and you'll got a Lt of answers like "I worked picking tomatoes when I was 10."
The rich get to go to private school, the poor get to sell their children off to robber barons. You would not believe how many parents out there are eager for this too. A good portion of the GOP are abusers that dont really care about their children and if they can force their children to go out and get a job so they can take their paychecks, they will.
That's why they are pro-birth and anti-education. This is why we still dont have year-round schooling because "traditionalists" want to be able to make use of child labor.
If you dont think it is coming, almost every red state has attemptdd to repeal their states child labor laws for agricultural and factory work.
