Ultimately, there is no objective reason that anything should happen a
particular way in the universe. I'm sorry, but you can't ever possibly
objectively say that any way for a society to run is correct. It's all about
our instincts and morals, in the end.
Food for thought: I'd wager to guess that you would be opposed to, say, a
totalitarian monarchy where everyone but the queen works as a slave for the
rest of his or her life, the men being forced to help the queen produce
offspring and the females being forced to forage for food and build
ever-larger monuments. I think you would be right to call such a system
unethical. And yet, this is entirely normal for most ants.
All kinds of things we humans would never permit due to our sense of morals
are perfectly normal or even necessary for other animals. A few ant species
base their survival on murdering the queen of another ant colony and
enslaving its workers. Cuckoo birds are placed in the nests of other bird
species, where they then destroy the unhatched eggs legitimately laid by the
nest maker and trick said nest maker into acting like its mother. The list
goes on.
Ultimately, it simply isn't objectively correct that any given society
shouldn't be a run totalitarian, oppressive dictatorship. The only way we can
say anything is wrong is with our sense of empathy, which we instinctively
formulate into principles, morals, and ethics.
