Like, I get the desire in a hypothetical, that you hope that people in power would use their power to make public schools better if their kids were forced to go there.
But in reality, the actually powerful can just pay for private schools out of pocket and the vouchers help a lot of middle-income families send their kid to a school that can provide a better environment for whatever definition of better is relevant to that individual.
It just seems like such misplaced anger and energy. You could just advocate for improving public schools, without attacking regular families trying to do their best while trapped inside a system they have very little influence on.
