I don't know how schoolteachers manage to do what they do and do it as well as they do, given the obstacles tossed in their way by politicians, bureaucrats, special interest groups, ideologues, social experimenters and assorted other navel-gazers - none of whom could carry their book bag. They sure don't do it for the financial reward. That, we save for semi-articulate professional athletes and Hollywood liberals who earn obscene amounts of money pretending to be someone else.
