It will still work if the private schools can expel students for behavior or academic issues. If they can not or will not do this you are correct and the "private" schools will turn into the same cesspits.
I agree. And if private school won’t maintain academic quality and discipline, I wouldn’t want my kids there anyway.
“It will still work if the private schools can expel students for behavior or academic issues.”
Will the schools, who will be receiving government money for these students, going to kick out troublesome kids, most of whom will inevitably be black?
