@SteveJohnson That's what we did here.
what happens is that the best-performing public schools end up having entrance exams. and people too poor to afford to send their kids to these schools suffer. and people say, aaa, who asked you to be complicit to your children's suffering? you should cut off your limbs to send your kids to these schools when other parents can get Daddy's driver to send to school.
which was why this toot-storm started, if you look it up.
