MOSTLY BECAUSE, they claim, it takes money away from public schools. Sure, the money follows the student, and gets a child educated, so why should it matter? And, still and all, when all’s said and done, if the reason a parent wants to send a child to private school is that the local public school is failing him, shouldn’t the public school lose the money?
OH! NO! Have to defend the system at all costs. Even or especially if the system is failing so badly as to be actually causing massive harm.
But also, possibly most important, the real reason rich and privileged people send their kids to private schools is to keep them away from all that lower class riff-raff. Can’t have them sullying our hallowed halls!
