Indifference works great for me.
It might be an unpopular opinion, but if I'm honest with myself, I don't really GAF any more, and IMO it's really too late to turn back the inevitable. Glubb's short essay, "Fate of Empires" is worth a read or listen, it's about 100 pages and free pdf and YT audiobooks are available.
One thing about being inevitable that Glubb identifies is there are often reactionary responses to the decline which are NEVER successful in stopping the decline; at best they will only slow the process down.
If you're in the USA, your ancestors likely left their homeland for a myriad of reasons in search of a better life here in the USA. I don't see anything wrong with doing exactly what my ancestors did, at least the ones that came here of their own choice (my Scots ancestors didn't have a choice during the highland clearances after the '45).
I've already planned my exit strategy. You can stay and fight if you want, you will lose as all others in history have lost. It's inevitable. If all goes according to plan, I'll be getting my oceangoing sailboat in the next few years, and a second citizenship which I will use if or when the zombie hordes come here, or our ruling parasites go full totalitarian mode.
enjoy the decline.
