I'm skeptical of this to be honest. The global employment market is a free market (of sorts), and so people will happily pay more for employee they perceive to be better whether they are or not. People still buy Rolexes, iPhones, and Teslas despite there being cheaper alternatives that do exact same things. So companies will hire employees they perceive to be better simply because they share a nationality. While I don't think it'll prevent every job from outsourcing, the high earners will flee to the unequal income areas to spend their wealth. If we see more equitable income in both countries (so to speak), it'll be far in the future if at all. Boots on the ground says internet connectivity in service-based economies remains unrivaled compared to the agricultural and industrial economies often touted as the outsourcing alternatives.
