As evidenced in this headline: "Americans enjoy less economic mobility than their peers in Canada and much of Western Europe."
We already know our health is worse despite our spending twice as much on supposed healthcare (more like health insurance and medical corporations' profits) and our educational system worse (not because of teachers unions but because in those other advanced democracies teaching is a profession on a level with other professions like doctors and lawyers and paid and respected as such) and so much more, but especially that our economic inequality—the gap between the wealthy and the rest of us—is greater, actually more in line with the worst undeveloped countries (many of the developing ones are now doing better than us in this area as well).
This can all be traced back to the Reagan years and his administration's policies and the rise of the right in the Republican Party.
If only the Democrats would use these facts in a simple and coherent and unified way to gain control of Congress so they can finally reverse these trends.
(And yes, the Dems are partly to blame as well for caving in and going along when the rightwing Republicans gain power and if I had my way Bernie Sanders or Elizabeth Warren would be president and have their own party and candidates for Congress, but peace of mind and heart in my experience comes from accepting reality as it is in the moment even when working to change it, as I hope I always am.)
