When the idea of rewards enters the picture, and people see others being rewarded more than they are, suddenly everything becomes unfair.
That said, I do think that the balance of wealth has become so wildly disproportionate in the world today that there is something to be said about a certain bit of unfairness behind the economics of things and even about the workings of this blockchain to some extent.
But fair or not, consistency and work (hard or not) are necessary for most people to acquire and then hold on to things of value and positions of rank.
