What are the flaws of the American education system?

In his book "Tenured Radicals" Roger Kimball wrote in 1990 that "simply describing what goes on in the academia today often produces blank incredulity in those not acquainted with its workings. ...I regret to report that the situation is far worse than they are ever likely to have imagined." Indeed, and things have only become worse in the twenty years since Kimball penned those Words.

This is such an important subject that I won't pretend to do it justice here, but will merely mention the grossly disproportionate number of liberal teachers in our educational system. The liberal to conservative ratio in our colleges and universities is essentially the exact opposite of the conservative/liberal Demographics of America.
