there is, of course, already a bit of segregation w/n many public high schools themselves - AP programs pretty neatly concentrate the folks w/ problems like you describe into the "regular" classes (and that's my rice-bowl! ) - folks like me than have to figure out how to make it work best for that crowd (hint: as much as it hurts me, we don't get to read much hobbes, locke n' smith in all their glorious length )
still, just like "breakfast club," even the smart bitches gotta rub elbows w/ the proles occasionally in shop n' pottery class, and that's probably a good thing (shit, the biggest trouble i got into in school was always in those classes, and that's what made them great! they also helped reaffirm my raging adolescent sense of superiority )
the bottom line is, society must deal w/ it's problem elements, the cripples, bastards and broken things that are, for better and worse, part of us (and hopefully not by just building the walls of our prisons higher and higher and higher)
