Here's the summary:
First the author states that everything the fed has done has been necessary and has been applauded.
Then the author gives a keyensian/monetarist argument about why monetary policy must be independent of politics. The author implies that knowing what the fed does would somehow take away it's independence. (not sure how this would happen...)
Then the author argues that monetary policy is too complex for anyone in congress to understand, and any congressman who thinks they can understand it is a fool.
