I know about Germany, I have relatives there.
You still have not answered my question: do you endorse prison and the government abduction of children for failure to comply with the state’s mandate on education?
If you home-schooled your kids in Germany in a lousy way, and they could not get real employment because the whole apprentice program has to function in one-single fashion...then the state gets stuck with losers. Trust me...there’s probably half-a-million losers already on public welfare in Germany, and based on the tax, and social care system....you have to support the losers.
So yeah....if you can’t depend on all parents to do the right tutoring or instruction...best to funnel the kids through the system that delivers. Because otherwise, you just add another layer of losers onto the employed folks to support.
