OK, so, following GPs argument, would that justify making kids work without asking them if they wanted to?
The point is that allowing kids to work is clearly not as egregious as forcing them to attend prison-style schools, and yet we punish the former and support the latter.
There is no argument that you could followning from what OP said. I have never seen anyone argue that kids consent to school. It does not exist. I did heard about some homeschool parents claiming their kids wanted it that way, but even that came from homeschooled kids unhappy with that decision (meaning biased narrator and heavily self selected group). Homeschool parents I heard talking said they think it is best for kids.
> forcing them to attend prison-style schools
That is not true for most kids. If your parents pay for one of those camps for troubled teenagers, then it is prison like. If you commit crime then yes, your school will be prison. If you have enough behavioral issues to end up in one of those special schools, it gets closer to prison.
But no, schools are not prison like for overwhelming majority of kids. Going further, majority of kids has neutral or positive attitude toward schools. Some hate it, but they are minority.
