On occasion I think HN goes overboard on the reward side of entrepreneurship too, and that's not right when that happens either. Tell the truth, let people make up their minds. (And to be clear, I mean it just happens sometimes. On the whole there's too many people doing it for real for raw cheerleading to go unchallenged for long.)
People have been getting led on about the value of their degree for a while now. The economic situation is bringing things to a head but it's not new.
Also, I doubt this is a serious call for a refund, in the sense that he has even the remote expectation of one. This is a warning to others dressed up with a rhetorical flourish.
That said, this guy doesn't seem cut out for the trade in the first place, although it's possible that that I'm wrong and this is actually a shrewd exercise in personal branding.
So it's quite different than what happens to entrepreneurs, they can fail and comeback several times, tabula rasa. Someone saddled with student debt is forced to live with that choice until they pay it off or they die.
I doubt he will be refunded, nor do I think he should.
