The financial picture Dalio paints is the first stage of this, but it merges with a lot of other trends to make something horrible. There's the ongoing migration crisis; conditions are becoming inhospitable in areas like Central America and the Middle East, which is driving migrants to developed nations like the U.S. and Europe and destabilizing those countries. There's the climate crisis, which is the root cause of the migration crisis. There's a trust crisis propagated by the Internet and Big Tech, where nobody knows what to believe anymore. There's a pending military technology shift where cheap autonomous weaponry fundamentally changes the power balance between large nation states and small insurgencies. And then there's a population that's just fed up, as evidenced by the Capitol Riots and lockdown protests (as well as plenty of Internet vitriol).
Unfortunately fleeing the U.S. won't do anything for this, because if the U.S. goes, the whole world will erupt in flames. Better to put down roots in a community whose values you agree with, ideally one in a well-defensible location with plenty of natural resources.
