What I mean is the idea functions as an ideological cover for their behavior. A King isn't just some brute who has monopolized force to impose his will, he is the elect of God himself, divinely ordained to rule. A cutthroat businessman isn't just a psychopathic scam-artist, he is an intrepid individualist not held back by backwards collectivist concepts of morality. Nobody wants to think that their privilege is arbitrary, so they create an idea to tell them that they are exactly where they are supposed to be.
