Summers’s outlook on economic policy can be summarized by the remark that he gave me some years ago: “If I had your views on economics, I would find another profession.” He meant that if free markets usually worked well and the government ought usually to stay out, then he would find economics to be an uninteresting occupation. Fortunately for Summers, he has always believed in the potential benefits from governmental activism, although the strength of this belief may have diminished over time.

My views are more akin to the nineteenth-century liberal philosophy espoused by Milton Friedman, especially in his Capitalism and Freedom. In that work, he proposed many policies that are harmonious with free markets and are receiving serious attention in the United States and other countries. This list includes school choice, the flat-rate income tax, rules for monetary stability, privatized social security, and the elimination of affirmative-action programs.
