Specifically it’s bad for rich people who own offices, but good for rich people who own businesses that don’t need offices and now aren’t expected to waste money on them.

The issue is that office space is leased for several years at a time, with the shortest leases being something like 5 years. It looks bad on the spread sheets when you have 3 years left on your lease, yet you’re not using those offices because people want to work from home, so a lot of companies are trying to force people to go back to offices so they can get their yearly bonuses, even if it costs the company millions doing so.
