Aristotle,
Politics — Book Five
“ It is absurd also to suppose, that a state is changed into an oligarchy because those who are in power are avaricious and greedy of money, and not because those who are by far richer than their fellow citizens think it unfair that those who have nothing should have an equal share in the rule of the state with themselves, who possess so much-for in many oligarchies it is not allowable to be employed in money-getting, and there are many laws to prevent it. But in Carthage, which is a democracy, money-getting is creditable, and yet their form of government remains unaltered. ”
