I live in a European country and our salaries will not go down nor do I expect any layoffs. Your question is very US/Silicon Valley centric.
Given the rise of remote work, cultural proximity, excellent English skills in Europe (I even heard that there's a country that's full of native speakers although they do have a slight accent and an obsession with tea) this might not work out so badly for _some_ developers.
It's why Fed/ECB targets 2% inflation, to keep the treadmill moving.
