but it's not a quest for perfect fairness - rather an attempt to maximise benefits. $300B in a vault, whilst millions starve is pretty obviously unfair, and actually detrimental to society overall. generally, when inequality grows, so does societal instability and discord.

At some point, we as a society have to argue with the American Ideology of "free markets for ever, for everyone, for everything."

It simply does not bode well for our species in terms of morality, survival or many other metrics to have people dying of thirst while another man washes his collection of Maybachs.

Some inequality is inevitable. Too much inequality is a disaster.
