it is not 'our nation's central bank'.
it is 12 parastic banks that are private that act as overlords over monetary policy and the money supply, meanwhile issuing money and doling it out to their friends and picking winners and losers. Their methods of 'free money for just our frens' makes it impossible for people to compeat in most industries.
they are not owned by the United States, they are private and they are parasitic.
