With mass production, all the computerized robotic production equipment, massive motor vehicles for mining and farming, ATM machines, self check out, etc etc etc, the entire world population COULD be having a lot more time off for pleasure. Writing books, inventing new products, or works of art.
The early pyramid building like WW I, and WW II, Korea, Vietnam, moon landing, space shuttle etc created too much unneeded wasted materials and wasted man hours. We could all be living a lot cheaper without all the taxes (man hours) required to do stupid things.
What good was going to the moon? Or WW II? Massive millions of people being led by the nose by small groups of very powerful special interests “pharaohs”. The pharaohs need to be buried. 🙂
