He isn't just sticking you in a bucket randomly. Your language on the subject has an emotional edge that goes beyond dispassionate observation that college education may be overvalued. It actively pushes the reader toward the conclusion that you actually do have a dog in the fight, and the college system has somehow wronged you.
I don't know if it has, but based on said language, I'd be surprised if it hadn't.
My perspective:
Having gone to CMU CS, which on the one hand doesn't have particular brand recognition outside CS, but on the other hand is fairly good at CS as undergrad programs go, I believe I can say that I probably did get 100k and possibly even 200k of value out of the education, quite aside from the piece of paper. A lot of the teachers I had were really seriously excellent (and I don't say that lightly), and I wouldn't have been able to learn from teachers that good in that array of subjects (field theory, abstract algebra, robotics, cryptography, etc) as well in any other situation. Yes, I could have read wikipedia and the lkml and so on, but, having done both, classes from really really good teachers work better.
On the other hand, I think I got lucky not only in terms of the ratio of program strength to brand recognition, but also in which teachers I got within the university; if I had taken different classes in different semesters, I believe I could have done a lot worse. Not remotely all the teachers were good or even passable. And, I could easily imagine getting very little value out of the experience, and I bet a lot of people, particularly ones at big-brand institutions, do overpay for the education they get.
The point is, it's a complicated question. There clearly is some value in some undergrad programs, and there also clearly is a problem with rising prices. Comparing it to a con scheme is not really doing it justice.
