A lot of people pre-suppose that “wealthy inequality” is a bad thing. But not everyone agrees, and many people think the greater good is served by things that might increase “the wealth gap” as a side effect. PG’s essay was exploring that very thought - maybe we want a higher Gini coefficient, maybe it’s good that vast fortunes are being accumulated by young tech entrepreneurs who provide goods/services that almost everyone in the world wants to use, maybe this is what the more dynamic and broadly enriching economy looks like, compared to the stodgier, class-divided alternative.
