So how has U.S. productivity grown recently? Unfortunately, very slowly. After averaging 2.7% productivity growth from 1995 through 2002, annual growth of productivity in the nonfarming business sector has slowed dramatically — to just 1.7% in 2005, 1.0% in 2006, and 1.4% in 2007. At this new average rate of under 1.4%, it would take nearly 52 years for average U.S. living standards to double — versus just 26 years at the earlier average. Signs of this slowdown are apparent, particularly in the waning competitiveness of U.S. sectors like automobiles, financial services and information technology.
