Actually, co-habitation increases the liklihood of divorce since couples who live together before getting officially hitched tend to place less value on the marriage "contract" and bail out when they hit a sore spot. I don't think it's a good thing for society in general, although that makes me a total hypocrite since I live with my girlfriend.

I can't imagine shacking up in college or the parents condoning it. I would think that the kids wouldn't do it out of shame, but then again there is no shame anymore.

If I was a parent, if you want to shack up and play house, then you can pay your own tuition, room and board.

I do too (meaning I have cohabitated with my current girlfriend) but I don't see what you mean by the "sore spot" reference. If things don't work they don't work. That's not bailing out, that's making a rational decision not to be married in the first place. My guess is that it's the same issues that would result in divorce later, so it's better than they break it off after merely cohabitating than if they signed a marriage contract and breached in later.
