If you are referencing property taxes funding schools, you should know that it actually only funds about half of total school funding. The other half comes from federal and state governments and the way they give out funding is to selectively counteract that misallocation such that 47 states actually allocate more per-student funding to poor areas than to wealthier ones and according to this article [0], it has been this way since at least 1995.
I said state and federal: "Considering federal, state, and local funding, almost all states allocate more per-student funding to poor kids than to nonpoor kids, though only a few—Alaska, New Jersey, and Ohio—are highly progressive. A handful—Nevada, Wyoming, and Illinois—are weakly regressive, and the majority have a weakly progressive distribution of funding to poor versus nonpoor students."
