Problem is power, not money
Before money was invented, the king knew he was king and the slave knew he was a slave. All money does is to give a numerical value to the levels on the food pyramid.
The Pacific Northwest Indian People didn't have access to metal until they were invaded by white people. Because of the climate (rain) it was difficult to preserve and store food and goods that they could manufacture. There was an old saying, "When the tide went out diner was served." In other words, fresh food was easy to obtain and life was relatively easy. Under the potlatch economy, one gained stature by giving stuff away. The potlatch was an intertribal feast. The tribe who gave away the most stuff "won."
But the Indian People had the same sort of social pyramid as did the white people. The Chief knew he was chief and the slave knew he was a slave. This, I think, is why people with billions in invested assets don't retire and enjoy life. Their enjoyment comes from having life and death power over the people on the bottom of the food pyramid.
The family with 20 billion has power over the family with only 10 billion. The "old money" families must hate Bill Gates, who claims his children will not grow up to be billionaires.
