Frontline had an interesting documentary on this industry a year or so back called "College Inc". If I remember rightly, they even discussed one of the schools named in the suit, Argosy University (along with a lot of hard-sell tactics and high student loan default rates that accompany the for-profit industry).

It was an eye-opening program. Here's the link if interested: http://www.pbs.org/wgbh/pages/frontline/collegeinc/view/

I think Netflix also has the episode available for online streaming.
