I'm based in the rich Western world. Whenever I travel elsewhere, I'm amazed by the cheapness of labor. Humans would attend a gas station or fetch items in a store. Why? They're completely unneeded, I can do (and WANT to do) that myself. I always feel sad about these people, trapped in an economic system that forces them into useless labour when they could spend their time learning actually useful skills.
pretty degrading to call what they do useless we all need to do something
We've pretty much locked ourselves into an economic system that requires everyone to work, even though our productivity has skyrocketed many orders of magnitude. The end result is most people are doing meaningless work just because they have to in order to survive, and most jobs do not need to exist. This is true even in office work. It usually manifests as moving stuff from A to B and then maybe back to A. Basically, not creating, just moving. And not physically moving either.
