Thus it is thought that justice is equality; and so it is, but not for all persons, only for those that are equal. Inequality also is thought to be just; and so it is, but not for all, only for the unequal. We make bad mistakes if we neglect this for whom when we are deciding what is just. The reason is that we are making judgements about ourselves, and people are generally bad judges where their own interests are involved.
AristotleA democracy exists whenever those who are free and are not well-off, being in the majority, are in sovereign control of government, an oligarchy when control lies with the rich and better-born, these being few.
