> Every dollar in a billionaire's bank account is a dollar that could be in someone else's instead. This is true, but billionaires don't just have a billion dollars sitting in bank accounts. The billions in wealth comes from ownership of property and companies. Some of this may be considered "zero sum" in the way you describe (e.g. a billionaire that owns and rents out single family homes). However, I would guess the majority of that wealth is not "zero sum" in the way you describe, such as a warehouse robot (or the warehouse itself). What are you going to do with a warehouse robot? It has no value to you, or almost anyone else.
