Remote is a competency that as a business you develop team by team, position by position.

So is async (can we do this just as efficiently when people are in far-flung timezones?)

I want to sit in my PJs and work from home just as much as the next guy. But the reality is if you're going into the office 5 days a week they haven't figured out how to replace you with someone from India, Argentina, Canada or wherever else. The competition for your position is still georestricted. You just being there grants you a local monopoly, there are a million people who would like to have your job but they're not in the running because they lack the proper visa and can't show up to the office you can show up to.

Once you go remote and the company sees that it works just fine, your monopoly disappears.

Many objections were raised in response to my post, none were convincing. That is because no one wants to acknowledge that they're just labor and firms are literally profit maximizing machines, they either maximize or get swallowed/killed by a firm who did. None of this is new or radical, labor just hates staring it in the face because it's dehumanizing: they are a cost that the firm always wants to optimize away.

Welcome to capitalism.
