Another important thing to remember is that kids with parents who have enough money to even be considering private tuition probably have an easier time being involved -- they can pay a nanny, scale back work hours to be available for school meetings, be around to help with homework, etc.

Getting back to the higher education tangent for a minute, I think those who are worried about kids being indoctrinated with socialist views at private universities might want to take a look at what's going on at Florida State.
