What's the motivation for writing the article? To me, there's always some way to feel superior by pointing fingers. I think he's driving his own brand of elitism. (Somebody please accuse me of the same thing, and let's see if we can recursively create a singularity)
This article (hosted not insignificantly at standford.edu) is an absolutely textbook example of this phenomenon.
Articles like this one, and numerous professional interactions with people who introduce themselves as "Suzy Sue, I went to Yale" or "Marcus Markk, I went to Harvard"...and then repeatedly fail to perform up to the expectations I'd have for community college dropouts...I've never heard somebody from a tier-2 or 3 school introduce themselves in this way.
After so many of these kinds of experiences, when I hire people, a degree from a tier-1 school is an automatic mark against, not a mark for.
