We're the most educated in history, but many people decided to use that education to learn topics that aren't lucrative/in demand. Personal responsibility plays in a ton here, and some people made bad decisions. It's still simple/easy to get a good education at a state school, entirely paid for by loans, and come out with a degree that will allow you to pay those loans back in a few years. People who plan accordingly benefit in a HUGE way from the availability/accessibility of student loans, the barrier to entry is that much lower.
As far as SS goes, I'd be happy to see it fail but I'm also happy to keep paying into it without a guarantee of return in order to ensure my parents generation doesn't find themselves destitute. There are so many ways to plan for your future, having the government come in and force you to participate in SS is far from ideal. Not sure how my fellow Millennials feel about that, though...
