Children are easier to convince or coerce to do work that is prohibited.

I'm not sure your intentions with trying desperately to convince yourself that it's safe and reasonable to have children work dangerous jobs.

14 year olds can work all sorts of jobs already, they can make money and learn skills.

There is obviously a reason these laws were passed. So the evidence you are so sure does not exist has been around for a century. These laws weren't vibe based.
