It's a fallacy to think there are not good schools possible in poorer areas; they used to be quite common, and still are in many places: https://www.city-journal.org/html/irreplaceable-9836.html

Rich elites, which almost everyone on this forum is, imagine that the poor people in the inner city who want vouchers want to send their kid to some swanky rich kid school where everyone wears a blazer.... they don't. They want to send their kids to the ordinary private schools that would exist in their communities if they were able to afford non-public education.
