Then we are doomed as a country.
It’s not just black kids. My wife is a teacher (was in the public school system), so we know. There is no way can we throw away 1/3 or more of the kids, in all but the most rural parts of the country, for another generation, and have the country survive as something worthwhile. If that 1/3 were all in, say, Southern CA, and we could just chop it off, then maybe we could (survive). That would not be a very Christian solution, though.
Regardless, even in flyover country towns of pop. 5000 or more, there are often big problems in the public schools. We are in exactly such a place, and it’s a big part of why we home school.
See my post 176...
They are already "thrown away". These kids have no interest in school. Their culture is toxic and anti-white. They are hopeless as it is. Tinkering around the margins (academies, tougher disciple) hasn't and won't work. The tough love is to get rid of welfare. Welfare subsidizes all sorts of pathologies and allows the toxicity to continue, generation after generation. There is no easy solution. Welfare is the problem.
