Mamabear, many of us will stay here either by choice or will get stuck. Other parts of the world will have their own challenges, so you pick where you want to take your stand, according to your best information available.
What might be a good idea, if it can be arranged, is for those of us who do leave to stay in touch with those who do not, so that multiple refuges are set up in multiple locations, so that not all eggs are in one basket.
My friends, for example, would be welcome at my door in times of hardship, just like our immigrant ancestors often organized things in groups, and helped each other get established.
People from the old countries fleeing poverty, war, religious persecution, and other problems, did indeed go many different directions. They didn't all come to the USA. Some went to Canada, some to Argentina and Brazil, some in various odd corners of the world. Some had to move a few times before they found someplace they felt they could call "home".
For me, English language is not only NOT a necessity, but is actually a DRAWBACK. New Zealand for example would report my financial business to the US government. There is also the problem that a lot of international policy trends follow the English language. For example, most of the English-speaking countries were the first to adopt the "white list" (restrictions on the flow of crop seed), and the first to implement Rockefeller Foundation bad educational policies.

I can learn virtually any "Indo-European" (as the universities call them) language, although Polish might be a bit of a challenge.

(Polish is tricky). It helps that so many of the root words are recognizeable, and they all have similar grammars (compared to something really exotic, that is). Spanish will probably be the main one and that is relatively easy to learn aside from the large numbers of exotic verb tenses. I would guess that some of them are vaguely similar to those in French, which I can speak (though exotic verb tenses in French don't necessarily come to me all that readily!! But to tell you the truth, they hardly ever use them all anymore anyway).
The alphabet is almost identical aside from things like n with a tilda. For that matter, Cyrillic is pretty easy, and Devanigiri isn't hard.
6 months and you'd be fluent.
One interesting thing about new environments: new opportunities.
I happen to know some skills that are very rare in South America. I could live well again.
