Yes, but this is like the opposite of a tragedy of the commons scenario. Are you saying the companies do this in order to save the cities and real estate prices? That's likely not even a small factor at the bottom of the list.
Mix in monkey-see-monkey-do management of smaller firms, and of course straight up class antagonism towards workers, and you've got RTO über alles.
All companies act in their best interest and that’s kind of it.
I partially disagree: if necessary, rent out various parts of this office space to multiple companies.
For instance, MPK 2x are essentially airplane hangers.
