Of course they will get ‘fixed’ over enough time. Neighborhoods change. What is now the bougie upper east side used to be squalid tenements. However if all those bougie kids end up in a charter instead, don’t be surprised when performance doesn’t budge much.

You don’t need a for profit charter system to do that if that is the goal.
