The dregs, as in the bottom of the barrel, of the global developer salary band. There’s no need to jump to the conclusion that it’s a judgement on the country itself and look for something to be offended by.

Due to current events someone could say the dregs of reproductive rights include the USA. They’re not making a value judgement on the entire country.

The competition is among companies (and the salary they are willing to pay to attract devs), so "the dregs" are the companies paying those salaries, not the devs.

This is a VERY charitable reading of the GP’s post. They mention beating “people” not companies and talk about “the kind of devs that can move around.”
