There is an American expression: It Ain’t Rocket Science,which is meant to be a pejorative phrase to denote that if you fail to comprehend a somewhat easy concept you must have diminished cerebral capacity. I do not mean to imply this but rather use it to address some FED SPEAK over the weekend in which the American Economic Association provided lively discussion about the “SUCCESS” of the Fed’s policies for the last five years. There was point and counterpoint from highly acclaimed economists and thus ECONOMICS PROVED AGAIN THAT IT IS NOT A HARD SCIENCE. When Aerospace engineers build a spacecraft and design its mission they are sure of the spacecrafts return barring some unpredictable mechanical failure. AEROSPACE ENGINEERING IS PROVEN TO BE AN EXACT SCIENCE.
