I have no problem with this statement.
It is amazing we are doing as well as we are, by that, still the best economic numbers in the world!
I will agree that it is amazing we are doing as well as we are with so many of the Clinton economic policies held over by the Bush administration but stating our economic numbers are teh best in teh world is far from a factual statement. China is having an 8% growth year. Us economic growth byy the rosiest estimates will be arround 2% without any increases in employment. Some economists put that figure well below that number.
Further when you take out imports from teh picture one may even find negative economic growth but any such projection necessarily involves estimates that are not reliable as the hard statistical data is not provided. In short it can not be easily proven so is subject to question and is an unprovabe assertion on my part.
