“American [public] schools are failing because they are organized according to a bureaucratic, monopolistic model; their organizing principle is basically the same as that of a socialist economy.”

Proving the quote's point. I moved to a new part of the country when my family was still young. I once owned Montessori schools and was at the time home schooling. My eldest was nationally ranked in an individual Olympic sport. The new area would not let my child participate in sports or any studies as long as I remained home schooling. My child was almost 14 when I then started them in the nearby university.

My children flourished in Montessori school, then once we began travelling the world, home schooling, we later joined with other families who were in the same boat and formed our own little school to educate our children free from political indoctrination.  It was not perfect (nothing collective really is), but parents learned as much as the students. My children are better for it and lived an incredible adventure that no school curriculum could ever provide.

Some of the more 'liberal' of the teachers we hired started trying to expose our children to their form of social justice.  Without good parental oversight, teachers can preach their progressive religion all day without opposition. 

That's why it is so important that our teachers be possessed of sound morals — they should be wise, not fresh out of college with a teacher's certificate (that's a red flag right there).  Teachers are examples the children follow — blue hair and nose rings should be nowhere NEAR our children.
