The problem with your perspective is you are assuming children have independent wants and needs to work and can stand up for themselves like adult workers can. This just isn't the case.

Children don't personally decide to work, they are told to by parents / authority / etc.. and they are incredibly vulnerable as employees. Comparing child labour to lemonade stands is ridiculous. There are rules about children working in the family store etc.. and child labour laws explicitly account for this. Child labour laws are explicitly about preventing abusive conditions in factories, fields, and other hard, grueling jobs.
