If that is true then why do private schools outperform public schools in the inner city? It isn’t really close with the same kids and less money.
Pray America woke
But if you put 8 or 9 in there, they start changing the culture of the school. And the easier you make it to put kids in there, the less effort parents have to make, and you start getting more of the less motivated parents, who think this is a quick fix ("Oh, just put them in private school. They'll take care of everything!")
Now add vouchers that make it tempting for private schools to drop a lot of hardline discipline policies in order to keep the warm bodies there (and the money it brings.) Look, I'm not trying to stop this process. It's going to happen. I'm just telling you, I've already seen this in my area. There's nothing magic about private schools. They just are able to keep the worse students out. If they become greedy for voucher money, that will vanish, that's all.
In every case of a private school, there is at least one adult who cares enough about the child's education to place the child in a private setting.
