I have learned a foreign language as an adult (french) to some degree of fluency after 3 years but it's a lot of hard work and not something I would take on lightly on top of other all the other things I need to focus on as an adult. Also, I notice that different people are happy with widely varying degrees of fluency. Personally I couldn't see myself achieve the kind of easy fluency I enjoy in english in french unless I spent 10 more years living in France, and there is a huge opportunity cost behind such a decision. About your second point, I'm merely talking about people who would consider moving from the US to some other country because of the incumbent president's actions/policies. To me it seems that the vast majority of such people would not consider moving to Germany or Sweden for example, just because of the language constraints (unless they are german or swedish, which would constitute a small percentage of employees).
