These people (ITT Tech, Devry, University of Phoenix) are the startups in many ways. They were willing to take a risk when no one knew if there was any profit in private education and as a reward for that they’re making a big return on investment. But now that the doors are open to private endeavors and it’s clear you can make money there’s going to be competition and that makes everything better. You already see signs of this (Most notably in the incredible achievement that is Western Governors University: http://en.wikipedia.org/wiki/Western_Governors_University)
Right now there’s an artificial stigma that’s still keeping a lot of the internet based competition down but as that begins to fade there will be no way for companies like ITT Tech to maintain their huge profit margins.
