What is the point of this article?

I regularly read the progressive online magazine Salon. Lately the quality of the writing seems to be declining. There are too many articles on pop culture for my taste. Some of the articles are nothing but liberal rants. I welcome the liberalism, but I can rant just as well as the articles.

There have also been a lot of articles that I simply can’t make sense of, like this one The article is taken from another Web site, but it is typical of a lot of the articles I have been seeing lately on Salon. It contains footnotes, which makes the complex mess even funnier.

What exactly is the author’s gripe with the current education system? Not that there is not a lot to gripe about, but what specifically is the article complaining about? Is there something simple that I am missing? It cracked me up when, at one point the article says “to be clear,” and then continues with what strikes me as more gobblygook.
