The author (from their previous post) is primarily interested in US vs Rest of World comparisons.
I don't think it's fair, but the reality is that companies pay what it costs, and in Europe there are fewer companies willing/able to pay high salaries, so they are lower.
The thing that would bring about this change is more companies being willing to hire remotely, particularly in places like Poland.
Why are fewer companies hiring and competing on salary in Poland/etc than other countries? I have no idea, but that is the real barrier to higher salaries.
