Surely that depends entirely on your definition of the word “fair”. Is it fair that a lower income child is deprived of an opportunity to improve their life through education because their parents can’t afford it?

Ultimately the debate here is “should richer people have to contribute back to society to help the lives of the poorer people”? Of course you can say no to that. But the majority of society doesn’t agree.

At least in America aren’t school taxes extremely local? I’m not sure what you are suggesting actually happens, or at least you are exaggerating quite a bit.

Poor people typically don’t live in the same neighborhoods as wealthy people in America. Wealthy neighborhood public schools tend to have lavish facilities from the tax base, so it’s more like “wealthy guy X doesn’t want to pay for the very fancy facilities he isn’t even using”, not “wealthy guy X doesn’t want to pay to send his poor neighbor’s kid to school at all”.
