This might be a controversial opinion here and I don't mean to offend anybody, but the distribution of engineers' effectiveness is not the same around the globe

This might be a controversial opinion here and I don't mean to offend anybody, but the distribution of engineers' effectiveness is not the same around the globe. Thought exercise: what kind of profile would you expect of someone going into software engineering in a country where the good jobs pay 5x median wage (and ~25x global median wage) vs a country where the good jobs pay 2x median wage (and ~6x global median)? Thought exercise: what kind of skills and experience would you expect of a 90%ile senior engineer in a country that gets lowest-bidder outsourced contract development work, vs a country that is directly employing engineers in "cutting-edge" development?
