Anyway I think you're both wrong about this. The reason for RTO is two-fold:
* Working in an office is much better for higher ups because their job is much more talking to people than doing "actual work". If you're spending literally all day in meetings it is worth the commute to avoid Zoom. If you're only spending 1-2 hours in meetings it definitely isn't.
* They have a fear that people will do no work if they're at home. Honestly I think it's completely unfounded, and it's just as easy to do no work at work. But it's a real fear.
Actually I think hn_throway_99 has a point about them being worried about disinvestment too.
But it's mostly the fact that WFH is way worse for management than it is for the bottom rung.
For people early in their careers, face time on site can be invaluable. They get to learn from people who get things done, and emulate them (or not). On-site, they learn from both positive and negative examples. This is simply less effective through meetings only.
The counterpoint also ignores human behavior. The person getting promoted is likely to be the person who shows up every day and visibly contributes when compared head-to-head against an equivalently performing employee WFH. First time people managers will likely be expected to manage people where their boss can keep an eye on them before entrusting them with remote teams. This could create a career choke point.
the advantages you mention are real, but WFH is poor career advice unless you can compete on price with low-cost foreign workers who are just as remote as the person I am paying a US salary to
