I'm a firm believer that every society has exactly the government it deserves. For instance, the majority of the German people weren't innocent victims of Nazism - they were in the streets shouting "seig heil".
The same goes for horrible oppressive governments like in Iran and North Korea. Those governments couldn't exist without the consent of their people - or at least the peoples' cowardess and unwillingness to overthrow them.
It applies to the U.S., too. We're governed by a class of professional lawyer/politicians who work almost entirely for the special interests that pay them. That's the fault of the American people, because we let it happen and we're unwilling to throw those politicians out of office.
And ya know what - it's just as true for teachers and the NEA. The NEA is run by radical liberals because that's exactly the way many teachers are - and the other teachers are unwilling or afraid to put a stop to it.
