Most people are born with two eyes and the propensity to think. If nothing is done about this, chaos threatens the land. However, since they do in fact rule, those potentates have not much to fear, for they can command the construction and perpetuation of a state-supported and legally enforced system for the early detection and obliteration of antisocial traits, and thus arrange that witfulness and 20-20 vision will trouble the land as little as possible. The system is called "education".
