But humans can clearly survive on a local diet pretty much everywhere
That’s subsistence living. No one wants to go back to that. Nor is anyone stopping you from living that way. Land is cheap in the middle of nowhere. Communes exist everywhere.
People already love to eat or order out. You could have a cafeteria
A communal cafeteria isn’t what people do when “going out”. If it was what people wanted, there would be more cafeterias and fewer restaurants.
A major driver of this is advertising or “brainwashing” people to buy garbage they don’t need.
It’s easy to think that everyone is sheep except for yourself. I’ve now come to believe that consumerism is fundamental to human nature, not advertising changing humans. The proof is thousands of years of pre capitalism artifacts from archeology sites. People have always liked unnecessary “stuff”. People have always liked fashion and trends. People are going to be rampant consumers even if advertising and marketing were stopped tomorrow. It’s their nature.
The article was about production, not wealth. While Bezos certainly uses 1000x the production compared to a regular person, he doesn’t use the 1Billion times that his wealth represents. He doesn’t eat 1B cheeseburgers every day. So while you’d get more out of the 30% of extremely wealthy, it wouldn’t be proportional to their wealth and there’s only .1% of the population that’s in that category.
