If we saw even half of public school students go to private or home schooling, then the number of teachers and schools needed would likewise need to shrink. I can’t imagine that the same level of funding would go to public schools, if they didn’t have anywhere near today’s enrollment.
Tax money would not go to the schools in the amounts it does now, and we would see teachers laid off.
I’m not familiar with details of private school operations, however, I can imagine that there is far less bureaucracy or need to deal with politically correct dogmas in the curriculum. There would be no need to teach about “LGBT” issues, if a private school chooses to avoid such subjects.
Should teach how to avoid ubiquitous STD transmission. And how to avoid or stop left wing bullying.....trades...electrical...computer...construction.....business...finance...the insurmountable differences in world religions..not only the similarities..classics(history, literature, philosophy, languages)...physical health, physical training, competitive athletics, etc...all the things I didn’t want to learn(except sports)...but should have.
