Let's say the official richest people on earth said I have made enough money I am just going to quit and stop making money

When there is over 1 trillion dollars per hour minimum wage they will all be homeless due to inflation

Sure they might have houses saved up but those houses will be taken away when the property tax for 1 year exceeds their net wealth

That is why they have to keep on working to strive to be the richest because they will have to continue to aim for a new goal not to be poor
