>So why the rollback? Most of this rollback is being driven by Private Equity firms who are heavily invested in commercial rel-estate and without staff in offices that rel-estate is tanking.

I agree that a lot of the pressure for the return to office is coming from investment firms that risk losing their shirt in commercial real estate if it doesn't happen. These firms have a lot of influence at the top of major companies. There seems to be a battle underway between the working class and the investment/management class over remote work long term. It is interesting to watch.
