“Okay, I understand what you’re saying, but how do you educate the children of those taxpayers who have no money to begin with without some sort of “wealth distribution measure?”
If the government schools didn’t exist, the poor would most likely be taken care of by charity. There are many models of private schools educating the poor. E.g. Catholic schools in the U.S. in the late 19th and early 20th centuries.
I don’t rexpect the government schools to go away anytime soon, but given that the quality of education has become such an issue, I expect that fewer and fewer parents will put their children in them. Private schools and home education have become a status symbol.
Maybe we do need to change our approach. A friend of mine was educated in Hong Kong, and says the schools there are ranked and require entrance exams. If you don't score well enough to attend even the lowest public schools, you have to go to a private school if you still want an education.
