1) Can’t be forced. Won’t happen.
2) Most likely scenario to occur. Because if it doesn’t happen you’ll have tens of thousands of black and Hispanic public school children in failed public schools whose funding has been cut to there legal bare minimum. State politicians will be afraid.
3) Very unlikely as the neighboring districts won’t agree to it.
4) Won’t happen because it would require new laws in legislative changes. Their is no public will by elected politicians to take away benefits from school children, even private ones. Especially considering their parents are a strong and influential voting bloc.
