We’ve all seen these statistics before in one form or another, but David Cay Johnston does an excellent job going into more detail for us in an article he published late last month.  As he correctly notes, when things get extreme like this you ultimately end up with extreme social unrest.  Furthermore, as I have pointed out for years and years, this kind of disparity does not happen under free markets with rules and regulations applied equally to all.  It happens under totalitarian societies, whether fascism, communism or crony capitalist corporatism (which is the model in the USA).  It only happens when a very small oligarch class takes over the political process of a nation and then uses it to game the system.
