I would give Obama a "C." He gets an "A" for understanding this country's profound problems in education, health care, infrastructure, and economic competitiveness, and for surrounding himself with extremely skilled and knowledgeable people who know what to do. He probably gets an "F," ironically, in his ability to sell these ideas to the American public and to be angry enough, conniving enough, and frankly mean enough to get them implemented and understood.

We need economic policies in the U.S. that produce jobs, first of all, but good jobs, second of all. Believe it or not, Germany, a country characterized by high wages, strong unions, a social safety net, and so forth is the second largest exporter (after China) in the world. The idea that the only way to succeed is by eliminating vacations, sick days, worker protections, and so forth is simply belied by the competitiveness rankings produced by the Economist magazine's intelligence unit and by the World Economic Forum.

Lyndon Johnson (with Abraham Lincoln close behind). Johnson was able to get things done, to read other people, and to adjust his own approach accordingly. One of the reasons he has so fascinated biographer Robert Caro over the years is Johnson's consummate skill in acquiring and using influence.

I am increasingly convinced that people who have power are not necessarily smarter than others. Beyond a certain level of intelligence and level in the hierarchy, everyone is smart. What differentiates people is their political skill and savvy.

Knowledge is only useful if you do something with it.

We now live in an era of the permanent campaign - all marketing and messaging all the time. We clearly live in an era where the "truth" doesn't matter much - people tell lies about things ranging from the likelihood of "death panels" to the effects of the stimulus on saving this economy from a true calamity. In such a context, Obama himself needs to be "selling" all the time, as does his team, and also be more forceful in advocating their views. He needs to project that he and his ideas will win. And I don't think he has yet done that.

The single most significant change has been the globalization of labor markets. Product markets - trade in goods - have been globalizing for years. But now, with the reduction in communication expenses and the building of all sorts of IT infrastructure, essentially any job can be done almost anywhere.
