GenX/Millennial retirement communities abroad. There won’t be any SS funds left for that generation so they won’t be able to retire in the US.

I hear this a lot, and for decades - yet during this time US debt and spending has exploded, including things like covid stimulus, great recession QE, etc. We happily printed/borrowed/etc but when it comes to social security - gee you're just out of luck, no money left, sorry!
