"We don't see things as they are, we see them as we are." --Anais Nin

A manager who thinks physical access to employees makes him an effective manager is going to push for that, even if the data says otherwise. We see this in every industry. During pandemic the headline was 'productivity is flat or increasing with WFH', now it's 'time for RTO'.

It's also not just about management, it's about real estate. Companies including Amazon have paid billions for office space, including long term leases that will be very costly to break. So if they say WFH is the future, they'll have to explain to their shareholders why they signed for (apparently unnecessary) office space that's hurting the bottom line.
