Because the evidence of wrongdoing and evasion is so clear, and the effect has been so damaging, I have devoted a lot of pixels to the GAO’s horrendous “secret shopper” report on for-profit colleges, as well as the stonewalling about what caused the initial report to be so biased. A potentially even bigger story, though, is what appears to be the machinations of an unholy alliance of Department of Education officials, Senate HELP Committee chairman Tom Harkin (D‑IA), and Wall Street short-sellers hoping to make big bucks off the demise of for-profit schools. This Daily Caller article, and the connected video of Senator Tom Coburn (R‑OK), are good places to start learning more about this, as is the website of Citizens for Responsibility and Ethics in Washington.

The problems with understanding scandals like this, of course, are trying to get the truth about things that have gone on almost entirely in real or virtual back rooms; knowing what is legal and what isn’t; and just figuring out who’s who. Such scandals also reveal little about whether for-profit schools are actually more or less effective than other higher ed sectors, arguably the main public policy concern.

What this sort of thing does start to reveal, though, is just how far out of public view policy is often made, as well as how people try to profit directly from government action. In other words, it’s a great case study in public-choice theory, and just how un-Schoolhouse Rock Washington really is.

So I can’t tell you everything about who said what to whom. However, at the very least it is clear, for instance, that famed short seller Steve Eisman had a huge amount to gain by testifying that for-profits are bad and there is a “bubble” in proprietary higher ed about to burst. After all, were either the Education Department or Senator Harkin — or both — to use his testimony to attack for profits, as indeed they have, Eisman would have a highly profitable self-fulfilling prophecy on his hands.

No matter how you feel about for-profit colleges — and my feelings are decidedly mixed– learning about how policy is really made can be a very unsettling thing. In fact, it can make you feel more than just a little sick.
