I've been thinking similarly. Bertrand Russell once said: "there are two types of work. One, moving objects on or close to the surface of the Earth. Two, telling other people to do so". Most of us work in buildings that don't actually manufacture, process or anything. Instead, we process information that describes manufacturing and transport. Or we create information for people to consume when they are not working (entertainment). Only a small faction of human beings are actually producing things that are necessary for physiological survival. Rest of us are at best, helping them optimize that process, or at worst, leeching off of them in the name of "management" of their work.
