I'm not really sure what's more prevalent now days... posts that are overtly idealistic and herald a "follow your dreams" mentality or posts that are ridiculously pessimistic and taut the "your idea sucks so give up" dogma.

I would never tell a graduate to just go "get a job." The cultural mindset to build something independently (interdependently might be better wording) is extremely important. The payment and reward of starting a start up transcends that of funding and exit - the god damned fucking journey, experience, relationships, and lessons are rewarding.
