I do believe that running a country is different than running a business. Some people believed that it was Romney’s economic advisers who cost him the election. Columbia business school dean Glenn Hubbard is too much of a skeptic on China trade, and he was misguided when he advocated policies that would increase demand for housing at a time when markets were calling for less investment in the sector. Harvard economist Greg Mankiw supported a cheaper dollar, a policy that is damaging to Americans’ efforts to save and invest. American Enterprise Institute economist Kevin Hassett supported a misguided work-sharing idea where companies would reduce hours for some employees and create more jobs for others, missing the point that job creation comes from expanded investment, rather than slicing a finite pie.
