Keynesian economics cannot work on a global economic level. America imports much more than it exports. Money printed in the United States leaves the United States as cash and comes back as chinese t.v.s, computers, examples of finished products and raw resources like oil. The rest of the world is going to get tired fast of the funny money America is generating 40 billion dollars a month. Good thing we have debit cards or else we would need wheel barrels like the Germans after World War I to get a loave of bread.
