You again mention one neighborhood "affording." This implies that the poorer neighborhood cannot afford it, it being better teachers. Teachers are part of funding, which implies that poorer neighborhoods are not funded to be able to afford better teachers.
If you meant something different, then by all means expand upon your thought and tell us. I tried to take a guess at what you might have meant.
Rich areas are always going to have a money advantage, you cannot legislate that away.
If you thought I was being a smart ass then my apologies, that was not my intention, was merely trying to show how your comments could be taken.
