They believe that a college education should be free, so they behave as though it is. Where a college education free, then getting a relatively worthless degree would be perfectly fine.

I don't know. I'm getting my university education for free, but I still have living costs (which may be mitigated by a part-time job) and "losing" five years that could be invested in some relevant work experience. So if I was going for a useless degree, career-wise, I would be at least be a little worried.

I guess some people think that people like me should be living it up while they can, and not worrying so much about the future. But there might be a mortgage to worry about in 5-10 years, and buying your own apartment/house is becoming more and more expensive (which might change in 10 years, for better or worse). And even though I am well-off by world standards, the future seems more unsure then ever; having some sort of economic independence seems like something that is worth working towards.
