“Billionaires v. the underclass” is such an unsophisticated discussion. Markets have all kinds of externalities, equilibrium traps, information asymmetry flywheels, and hundreds of other phenomena that interplay to trip people’s sense of fairness in all kinds of ways.
To pick just one example, infinite scrolling can be seen as a modern equivalent of cigarettes— a product that made people billionaires, and that consumers obviously want but are not free to stop using because of hyper-sophisticated dark patterns.
Is Elon a trillionaire because he created a trillion dollars of value from thin air, or is it because he created an information asymmetry flywheel that lets him allocate capital more efficiently than other actors?
It’s genuinely unclear to me whether the universe in which we incentivize this kind of scale is better than the universe in which we do not (because the counterfactual universe has massive externalities too). But this is obviously not just a matter of compounding value creation and becoming a billionaire fair and square in ten years.
