Well, it's not as if Harvard charges them a lot of money to become that ignorant and indoctrinated. or that the government subsidizes them in the pursuit of such ignorance. So where's the harm? Gee, there actually was a time when young people walked INTO Harvard with skulls full of mush.
Now they spend four years there to come out that way.
There is truth in what you say. A study by the Intercollegiate Studies Institute a few years ago revealed that on a test of facts of American history, the average Harvard senior does worse than the average Harvard freshman.
In other words, it has been empirically demonstrated that Harvard makes you stupider than you were before you went there.
