If the teachers unions and the educrats of the Dewey school have taken over the educational system even baby steps over 100 years can produce a great geographical deviation. Apart from the PTA, who was there to bring them back on course? The entire incentive system is for a teacher to become an administrator and to do that by selling a whole new approach to a very old problem, teaching Johnnie to read.
I have long been concerned with the Odyssey that leads the country to the place where the Constitution has come to mean almost precisely the opposite of what it meant when it was written. These 180° reversals did not come as stunning pronouncements from the Supremes, they came in baby steps, one accretion adding one more deviation to the last. In this discipline, as in education, there is an unholy axis between the academics and the functionaries at the bar and in the courts. One might think that in an adversarial system there would be abundant checks but, as in education, the way to personal success is to make new law. The results seem similar.
In each discipline the accretions have made the professionals the enemy of the people and the subverters of children, Justice, and the Constitution.
