All I can say is there are a lot of people with 10-15 yrs experience who will happily accept $140-150k with 10+ yrs experience in the US remote market (more specifically full stack node/react)
I think it's unrealistic for someone to post "evidence" in this case. Not worth the risk of doxing/etc. Think all we can do is take people at their word, or explore the market ourselves and get data from our own experiences.
