Aren't private schools in the US monitored at all? I think they can be closed here if they aren't good enough or teach particularly stupid stuff. Some Islamic one was recently (although as no one had been stupid enough to send their children there it was empty anyway).

I don't know if turning your pupils into little socialists is that bad an idea. They'll still grow up and become rich and successful, they'll just be guilted into helping some poorer people too.
