> I have a feeling that many of the engineers who live in locations far off from SV such as Bangladesh, who do have the skills to make it as a FAANG employee (for example), already choose to move to SV/London/etc and collect that salary What is this feeling based on? You have to invest a lot of money, time and effort into paperwork before you can dream of migrating. One does not simply "choose" to move; it takes months or years of effort - not every talented individual takes this route, or even thinks it's worthwhile - there are a lot of trade-offs, even for the most naïve. I suspect this idea of talent=success is an instance of the Just-world fallacy (one way of reading what you said is that those who are talented have already been rewarded by FAANG jobs, therefore those who haven't yet are not talented, obviously)
