"Plutocracy is rule by the wealthy, or power provided by wealth. The combination of both plutocracy and oligarchy is called plutarchy.
In a plutocracy, the degree of economic inequality is high while the level of social mobility is low. This can apply to a multitude of government systems, as the key elements of plutocracy transcend and often occur concurrently with the features of those systems." - Wikipedia
What amazes me is that so many middle-class Americans have been duped into supporting American plutocracy. Namely the Tea Party folks, who have become the 'peasants for plutocracy'. But with the Tea Partiers I think their rabid racism is blinding them to what they are really supporting. The illustration above is a perfect picture of how idiotic the Tea Party movement really is.
