Nice article today by John Hussman entitled Superstition and the Fed, discussing the Federal Reserve and the role it plays. The psychological impact is far greater than the actually monetary one described.

Hussman goes on to outline the monetary system and how foreign central banks contribute to the changes to a greater extent than the Federal Reserve. Lots of good information about how the system works.
