I assume you live in the free world. Some socialist states in history, such as East Germany, pushed child-rearing and early education much further into the hands of the state through extensive state-run childcare and kindergarten systems. That model is gone, and for good reason.

Even with schools in place, the basic responsibility for raising children still belongs to the parents. Schools can support, educate, and compensate to some extent, but they cannot replace parental responsibility.

I also see far too much awful news — in my country, Korea, for example — about terrible parents harassing school teachers because their children are out of control.

i'm afraid that model is making a strong comeback in the so-called free world

I was born in a communist country in Eastern Europe, which is now crony capitalist. The issue is extremely complex, and all I can say in such a short paragraph is that ideologically-driven implementations are doomed to fail. It doesn't matter if you believe in "free-market", "the state", "free-speach", "socialism" or "equality", if you put these above the concrete reality of modern parenting, and how much harder it's getting compared to previous generations.
