Every profession attempts to erect barriers to entry to protect itself. Lawyers have the Bar Association and its rules for admission and ethics. Likewise the American Medical Association and other doctors associations. Such groups are very fond of jargon which further sets them apart from the unwashed.
This desire to protect one's turf extends to blue-collar occupations where unions seek to have a closed shop and to regulate the rules such as promotion according to their liking.
Every occupation, it seems, undertakes the lobby for government protection of its interests and we see a kind of cronyism emerging as regulatory capture applies even here.
Somehow, like most of the soft subjects where academics have attempted to create a "science" where nothing but art and jargon exists, pedagogues have managed to have created a closed shop which insulates them from pesky intrusions from taxpayers and even parents of the very children entrusted to them.
Why does it take a licensed professional or "expert" to know how to teach everything from arithmetic to algebra? If it does, we should fire the lot and hire a whole new bunch of professionals because these guys can't do the job-or spell wont do the job.
