Can't really blame the families though, if the schools in their neighborhoods are bad and they have the option to send their students somewhere better. Race has nothing to do with it.
Exactly. As long as they're paying the same tax towards public education as everyone else, I don't see a problem. Whether it is enough or being used effectively is up in the air however.
You can certainly blame them if they vote in local elections to perpetuate this unequal system.
