For example, if you were to trace all of Rockefeller’s fortune after his death, I would imagine most of it initially went to his heirs. But eventually, at least part of the wealth diffused out of the bloodline, and if you were to go through and account for the physical utility of that money, what would it look like? Labor to create superyachts and exotic sports cars? New buildings on college campuses? Cancer research?
It would be nice if we had a system that quantifies this somehow, because in addition to the problems created by wealth inequality, I would argue that there are sufficiently many inefficiencies in most governmental bureaucracies as to result in a similarly poor usage of money as a billionaire who spends some of their wealth to construct a mansion on a private island.
To play devil’s advocate, suppose we have a hypothetical billionaire that never spends any of their money on luxury or excess but rather devotes most of their time to figuring out how to use their wealth in a way that extracts maximum humanitarian value from it. You could argue that what constitutes “humanitarian value” is totally subjective and that decisions concerning such a large amount of money shouldn’t be left to one person. But on the flip side, would you say that most governments succeed at representing the average person’s desire for utilizing tax revenue in a way that optimally benefits society? Do they accomplish this efficiently?
I don’t know the answer and don’t really have a strong opinion either way without further research, but sometimes I wonder if despite the problems they cause, billionaires sort of represent the “exploration” part of “exploration vs exploitation” in reinforcement learning, as they slightly destabilize a societal system that might otherwise be stuck in a rut or a local optimum.
