It is an option and they will, it will start slowly though. First offering a job to someone out of state. Maybe they save some money and the next hire, they look à little further and they pick up an employee from another English speaking country, they save even more salary. The more these tests work out the more companies will expirement. Eventually hiring an American will seem unnecessary and costly if you're distributed anyways.

It's great news for non-Americans though, USD goes a long way in a lot of the world.

Last time I was at a company that tried that, the (US-based) management would fight over making sure their projects went to the US-based devs (even if not in the same office) vs the overseas devs because the communication gap - timezones and physical distance both - was that bad.

Zoom hasn't fixed this.

It becomes a lot easier as an office becomes remote-first, and adopts the changes necessary to make that work well. There's no longer that barrier between the in-person and remote teams.
