Earlier quoted context omitted.
There is no "should" there are only "is" or "is not" The universe has no need to be fair.
> The universe has no need to be fair. Human societies have a strong need for fairness, however. Unfair societies collapse.
I don’t think we have the data to disprove the stronger claim “societies collapse”, and I don’t think being unfair (whatever that means) makes societies collapse earlier. Did slavery hasten the fall of Rome, for example, or the Gulag the fall of the USSR?
As to “whatever that means”, I think that’s hard, if not impossible, to define objectively. Catholic dogma says the Pope is the representative of god, for example, so catholics (less so in modern times, I think) don’t question his decisions. Many would call that unfair, even if the pope would be elected 100% by merit.
