The best and brightest of Asia and Europe move to the US because of the salaries. Thus, the talent pool in the US becomes far stronger than the talent pool in other regions. But it's also true that FAANG all have global offices and teams fully in places with lower salaries. They are aware of the pay differences and take advantage of them. But they can't completely have all development done in a separate time zone or even same time zone separate region (like LATAM). That slows down dev cycles, invites gaps in product understanding, and allows you to miss out on top talent who will move to get paid top dollar.
