"Charge infinity for college" is the best way I've heard this put. If there is no pressure on a school to control costs then nothing will control costs.
However, this does not make it just. Education should provide you with a huge economic surplus. That's the natural order of things. It's very unnatural to say "I educated you, and now I hope to collect 99% of your economic bonus, but you will still be 1% better off so it's a good deal for you". That's called slavery.
This seems to be a common attitude though, on the scale of one (developed) nation to another (developing) nation. That is, I'm thinking of the anger over "intellectual property theft".
