I have read articles about it, but it's very hard to Google for it. It would be hard to research, too, because the schools are complicit. They want these students to get their rubber-stamp diplomas for $250k+ and then leave the US. There would need to be some huge third-party investigation with subpoena powers over the schools to uncover all the fraud. So for now, it's anecdata that seems to ring true for anyone I talk to who gets near universities.
