For example, consider John Stewart - he's somehow made a shtick of mocking the establishment while somehow calling for them to have more power and deligitimizing anyone who is outside the mainstream.
Insofar as young people want "change", it seems merely to be going back to mythical glorious past era when a single person could support a family, have "health care" and engage in real estate speculation via the proceeds of unskilled manual labor. They believe this "change" will happen mainly by funneling more money into existing programs and bringing back a few policies from the recent past.
(Admittedly, the tech world is an exception to this. And my vantage point might be skewed due to spending my US life in NY.)
What change do you believe the young want today?
