This much is true. Most people don't do much work at work. The difference between working in the office and working remote is that when you're at the office, your "pretend to work" time is spent discreetly browsing social media on your phone. When you're at home, you can spend it on things more conducive to your health like going to the gym or walking your dog.
I have a hypothesis that the top 10% of performers (could really be as little as 1%) in society are usually very upset by the fact that 90% of people want to do as little work as possible, and those top 10% performers are holding the rest of us hostage via in-office requirements and constant electronic monitoring, but I think since 2020 these people are now losing that battle and the 90% no longer have to pretend to give a shit what the 10% think anymore
