* The US economy, at least for part of the populace, is pretty crappy; working three jobs, money worries, the financial crisis, it all adds up. * The internet; more (negative) news from all over the world, telling people how terrible it all is. At the same time, "Facebook Envy", people getting told how bad their life is in comparison to their facebook friends (which is skewed because a lot of people only put the good stuff on there). * People are dicks.
