I am going to do the HN thing and respond to the strongest possible interpretation.

And that is for me - there are people who inherit fortunes, who by virtue of having fortunes, and who invest in anything sensible, even an index, will never need to work and contribute, and are virtual kings. This is a hard kink to iron out in capitalism.

In addition those who have fortunes and decide to work hard may direct that work into getting more unfair advantages (lobbying, for example, to ban better mousetraps) rather than doing stuff for the greater good (making better mousetraps). I think this too is a problem.

Capitalism + government intervention + free speech/debate might be as good as it can be for now, until abundance.
