[remote work] hasn't really been a reality the way it is today. During covid, we were forced to implement norms and tools for remote working (like Zoom). Also, we learned about replacing an expensive worker for a cheaper one one at a time. Earlier, there used to be entire teams in some remote location, so it was similar to having 2 islands (one large, one small) with a bridge which was crossed may be once or twice a year during annual trips to HQ. Now with one-new-person-at-a-time, teams don't lose productivity but over time, American workers are replaced with cheaper ones.
Source: seeing it myself in my current company. Also remembers: shareholder class is ruthless. If I can see this, they are seeing and acting on it as well.
Edit: cannot reply to the unity1001's reply so editing here - sorry to break it to you but earlier, there were only tools. Covid forced us to implement cultural norms and processes to actually work with those tools effectively. That was missing before.
