I've seen several people point to this narrative on HN and it just doesn't make any sense. There's three possibilities as I see it:
1) There's some secret cabal of people who run the world and they've decided that commercial real estate needs to thrive, for some reason. So these overlords go to their puppets running major companies like Microsoft, Amazon and Dell and tell them they must make their workers return to the office in the name of propping up commercial real estate. Apparently some people on HN think this is likely?
2) The managers at Dell/Amazon/etc. feel the need to prop up commercial real estate as an act of charity. Rather than focusing on their own businesses, they are worried about their friends in commercial real estate. This seems even less likely than 1.
3) Managers at major companies believe that there are benefits to working together in person.
Why are people so reluctant to accept option 3? You don't even need to accept the premise that working from the office is better. You just need to accept that premise that management believes it's better to be a proponent of this option.
