Nothing short of nuclear war or Year Zero on a global scale can do that, I'm afraid. That, and even assuming we survive and rebuild from the Crisis of the 21st Century at all, a few centuries of (relative) peace and prosperity is probably the best we can hope for, given how short humanity's collective memory can be.
Despite that, America will almost certainly be well-remembered thousands of years into the future, judging by how the likes of Ancient Rome and Egypt remain household names today. Most people don't know much about them, of course, but even then, they're still vaguely aware that they were big players in the grand scheme of things that passed their cultures, customs, and contributions down to future generations who've long since built on them as a "foundation", of sorts. (e.g.: Roman law being the basis for Western legal traditions.) Whatever the case, I suspect the people of 20,022 will have
long ceased caring about the things we're fighting over, with terms like "Enlightenment" and "Progressivism" meaning about as much to them as
Guelphs and Ghibellines bashing each others' heads in do to us. (Basically, not much of anything, really, since people will have long forgotten about "Modernity" and moved onto issues of their own, by then.)
