Like much tech wealth wisdom, it's rationalization of their megalomania, their self-serving desire for power. Humans naturally desire power to varying degrees, but we have other desires and we have other things that limit us (e.g., our consciences, or Adam Smith's 'impartial spectator'). With enough real power, you can ignore these things and others will not only fail to check you, but will encourage you. Power corrupts.
