I found a picture of me in first grade. One teacher, about 30 students, we were having ice cream and cake in the class. All the kids were sitting politely, well-groomed, etc. In other words, we were raised properly at home before we ever set foot in a classroom.
I’m sure you’ve seen the devolution of how children are raised - and I don’t see an easy path back. Teachers spend an inordinate amount of time teaching students how to behave in public (whether conservative or liberal, the task remains).
I hate to sound conspiratorial, but I often wonder if that’s not the State’s agenda - leave the child-raising to the government, and it will mold them to its own purposes.
I think it is a spiral. Get taxes and prices up so both parents have to work just to stay even, get the kids in the schools as caretakers to extort more form the parents with the ever looming threat of a strike or sick-out, and keep the cycle going. The liberal agenda, cultural pollution, and even women's lib (don't you work, or are you a useless housewife?) all work toward that end.
