Millennials, I'd argue. During the 90s, culture at large painted a picture of stability and progress, all made possible by democracy. See Francis Fukuyama's The End of History for the kind of tone that permeated the time.
As we Millenials have gotten older, we too have seen through the veil and realized the system isn't perfect. More importantly, perhaps, we've seen the wide range of ways people react to this imperfect system. Some have chosen to undermine its very foundations to get their way, leaving many to wonder what we're left with if -- to loosely quote Whose Line Is It Anyway -- the rules are made up and the points don't matter.
The late 70s through the 90s were kind of our last stable period (the 60s & early 70s were tumultuous with Viet Nam and Watergate, and the 30s & 40s were dominated by Depression and World War). That all starts to unravel with 9/11 and the response to it (starting wars in Iraq and Afghanistan that cost us $Trillions and didn't really help stabilize the region and ironically began the destabilization of the US).
Much as we like to kvetch about Clinton (and I've certainly done my share of it, and certainly much of the criticism has merit), if there was a "golden age" of America in recent memory, the Clinton era was it.
