I think it all depends on incentives. If one goes to school with a sole purpose of learning something(employment, career track being non-issues), I'd imagine, they wouldn't care about the cheaters as they wouldn't be competing with the cheaters for jobs, promotions etc. This reminded me of a Russian pop star from the early 2000s who became a philosophy major at a major Russian university. Presumably, she didn't mind the cheaters as I doubt she was aiming at tenure track or something to that effect at the school. Although, I can't be sure :)
