A proper education isn't possible with a public school system when certain political ideologies are trying to destroy it
FTFY. Seriously, public school education can be fine until a bunch of demagogues try to privatize it or cut its funding to nothing. I've known so many teachers who busted their ass, cared about their students and did a great job only to be hamstrung and crushed by the useless administration above them (up to and including the Governor.) The uncaring and/or insane parenting doesn't help either. And please don't mention charter schools; I live in Florida and have a front row seat to that sideshow of greed and incompetence.
But in all honesty your overall point about the entire system circling the drain is probably correct. There are just too many short sighted and/or psychopathic people in charge. But there's still a glimmer of hope that the populace in general may come around and begin to value intelligence and reason again. Hopefully before the planet is reduced to a lifeless pile of slag of course.
