A four percent growth strategy means you fix a convoluted tax code. You get in and you change every aspect of regulations that are job killers. You get rid of Obamacare and replace it with something that doesn't suppress wages and kill jobs.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
