The way I see it things look like this;
human beings naturally (not artificially) dominate one another using violence or deprivation. Why is Daddy historically the head of the household? Because he uses violence to hold that position, could be Mommy's the head of the household for the same reason, or either one of them could use deprivation instead, this is all abuse, it is all ethically wrong, but it doesn't seem like there's any other way that people as a whole are capable of being and so if you want the world to be a nice place where people say please and thank you and ask before touching one another then you are going to need to attain dominance, so that way you will make the rules and your rules will say that everyone has to be nice and since you are in charge they will have to be nice and that is the way humanity works. Of course you will have to be on the lookout for those looking to dethrone you.
