I’ve always quipped that the idea that the highest property taxes fund the poorest areas, and vice-versa. While not feasible, the current situation is absurd.
Well, that's effectively what happens in European systems, where schooling is basically run entirely by the State and funding is mostly distributed on a per-pupil basis - higher-income taxpayers effectively subsidize poorer areas. So it is, in fact, feasible.
But Americans would probably call that illiberal or something.
Most Americans would call that pretty much how things actually happen here, too.
