You can't fix a broken system by becoming part of the system. Many critics of public education have set up their own systems, of course--the whole charter school, Montessori, and homeschooling movements for example--but right now the best bet is to rescue children from the public school system and put them into something better.

Even if you can fix the public school system, becoming a teacher is not the way to do it.
