There are a lot of reasons that the current generation has to be angry with their parents. They've destroyed the economy, the jobs market, and are well on their way to destroying the planet. They'll retire in the next decade supported by a ponzi scheme (social security) on the backs of their children. The world is less safe, less secure, and more violent because of them.
I can't help but look at Japan in the 90s and think that we are in for a repeat of that. An aging workforce, being constantly downsized and outsourced. No new jobs for college graduates, so they must live with their parents until their 30s or 40s. Property deflation over decades because their parents refused to acknowledge the losses on their overpriced houses. The parallels between Japan in the 90s and US in the 2010s are eerily similar. Study their culture to see what is next.
I don't know what the answer is, but I can tell you that if the younger generations don't get involved in politics, the world will be destroyed by the older generations before we get a chance to truly participate.
