Wealth concentration

A plutocracy () or plutarchy is a society that is ruled or controlled by people of great wealth or income. It can be considered a form of oligarchy (rule by the few) where the ruling few are wealthy. The first known use of the term in English dates from 1631. It is not rooted in any established political philosophy.
