> if the majority of parents do not care to educate their children.

I don't agree that this is true. I might agree that a majority of parents now don't understand how to educate their children or have the excess capacity to do so.

Reading to your child means that you have literacy above your child as well as having time. Doing well in school presupposes that your parents know how to do well in school. Navigating bureaucracy is a skill learned by the upper-middle class and above.

Working the system is difficult when you spend most of your time simply trying to avoid having that system grind you apart.

Providing a public education to everyone is how society can help ameliorate some of those issues. It also is the most cost effective by a long, long margin.
