This has been happening for decades. The only maybe novel side of the story is that post COVID, there may be a hope that remote workers are paid at least respectable wages vs their head office peers living in extraordinarily expensive cities. That hurts the developed cities and countries more than the individuals though. Expect a lot of heat out of civic conferences the next few years as they start to re-assess their budgets/roles. Some equalization is only fair in the end. Your output / cost should be the same as any other. Not all developing economies have talent that can fit these companies today, but there's no reason that can't change tomorrow. The major gap from my perspective is fair and equitable ways of gauging performance (tech specifically but in general).
