Hello, I wonder, concerning unemployment stats, people are saying u-3 or u-6 etc. is there something like “full utilisation”? What would that look like? Say, assume drones/advanced future cyborgs are free and everyone works and likes it. It’s not going to be infinite growth since it would have to be locked to a pop and region. Simplify for example: it works out to be a Mac Donald’s every second street corner. How many jobs and res? I also heard of a thing called money velocity. ~how much a particular dollar moves around. I heard it’s worth considering when understanding inflation stuff. I heard it said that recent stimulus has been like adding gas to a cold system (low velocity) where last time it was a hot system. The worry is we are going to explode if the temp goes up. Have a nice day everyone.
