About the Word:
A plutocrat is someone whose source of power is wealth. The word has a root in Plutus, the name of the Greek god of wealth and riches not to be confused with Pluto, the god who ruled the underworld.
In a classic comedy by the playwright Aristophanes, Plutus is somewhat surprisingly portrayed as a beggar. Zeus jealous of humanity had blinded Plutus so that he would no longer be able to give out his gifts only to the deserving, but instead would hand them to the bad and unjust as well as the good.
