Don't forget environment.
But they leave very nice government debt behind, so millenials have something to solve after they pay out their student ones and pay boomers pensions.
Or perhaps the Neoliberal policies that are hard at work dismantling all the social safety nets that gave people hope and encouraged them to take risk without fearing that failure implies total ruin.
Boomers made the economy grow incredibly and had some busts along the way. They got up and kept going. The boomers are the most creative and productive American generation period.
Millenials are still living with their (wealthy) boomer parents, delaying marriage and waiting for their boomer parents to die, whereupon the millenials will inherit their boomer parents' wealth. Unfortunately this will fail, b/c millenials have neither a work ethic nor a saving ethic. In the end, they'll spend their parents money and the US economy will flat-line.
It's a real shame that boomers weren't creative or intelligent enough to prevent issues related to automobiles and climate change. It's also a shame they didn't come up with a decent fix for Social Security that will only benefit their generation and no one after.
