And that should change too. It should be so socially unacceptable to poorly parent children that it is only the very worse sort who do. Children should not be left with parents who cannot or will not feed them, provide them with basic necessities and those basic skills that parents traditionally have always taught their children, who will not set and enforce necessary rules. I'm not talking about parents going through a temporary bad patch but parents who are chronically unfit and unwilling to provide for and protect their children.
Toilet training was mandatory for first graders when I was in school.
