Lots of billionaires should probably be at the hague. But we should be glad if people can become billionaires because they are generating that much value of both parties being better off, without imposing externalities on others. Yvonne Chouinard came close to this ideal, I think.
If someone can genuinely generate billions in value, not just by imposing externalities on others that they then reallocate to themselves, I will be damn glad that they exist and be damn glad that the hope of getting richer keeps them at it.
