We treat children like that. Largely for the economic value they can provide by making them spend most of their awake life at school. If school wasn't needed, it would look barbaric.
Since public education became a thing for all the states, conservative Christians have been opposed to it. They will moderate their message depending on the audience, but when discussed among themselves they talk about abolishing it. The really ridiculous thing is how schools are funded. I won't go into it here, but it guarantees that poor people will have a bad education.
It is for many things but education (not indoctrination or brainwashing) is not one if them. Thankfully I realized this very early.
Some amount of education does occur, but it's incidental to social indoctrination, keeping parents' wages high by forcing kids out of the job market, etc.
That's America's choice to have a failing system, not a universal property of schooling.
Both public and private schools can be places where people experience violence, but many more people experience violence at home first.
Rein it in, minuteman.
What more could you ask for in a prison?
I hope you never see a real prison. I'm serious about this. They are horrifying.
By the way, what do you call a well-treated slave?
It does happen, and if I did meet someone that was forced into slavery, I would hope that I could find help?
If anything I was defending public school? What the hell are you talking about?
