In West African slums, the public schools are so bad that the slum dwellers send their kids to private school. Of course the tuition is adapted to the means of the local population.
Ok, and?
The town or village would decide that they need a school. They would get together, vote a certain amount to pay a teacher, and come up with a tax to cover it. Someone would be assigned to hire a teacher.
Of course, at this level of local-ness, everyone taxpayer knew everything about what was going on. Any problems were immediately apparent and were quickly resolved. Contrast with the current system, where Washington decides what goes on in every little neighborhood, and feedback is zero.
So the issue of private schooling has nothing to do with cost.
