One thing that I'm surprised is not happening more, and I'd love to hear your comments about the reasons, is the move of senior engineers from places with high cost of living to countries with much lower cost of living, specially for those that are already remote. Another person commented of such move but considering how much more disposable income one would have I'm very surprised this isn't happening much more often.
I certainly understand how complicated such a change is, specially if you have spouse and children, but the difference in purchasing power and cost of living is so dramatic that a senior eng making 120k USD per year could easily afford a nice house (mortgage), a decent(bilingual/international) education for the children, healthcare for the family (private that wouldn't bankrupt you) and would still have a considerable amount of disposable income for whatever else they think is relevant (I'm using south of Brazil, where I live, as a reference for that).
If you are in such position, have you considered it? If so, what is stopping you right now?
