It's actually a tribute to the quality of economics teaching that they have persuaded so many generations of students to believe in so much that seems so counter to what the world is like. Many of the things that I'm going to describe make so much more common sense than these notions that seem counter to what one's eyes see every day.

Poverty is what we call the extremes at the bottom.

During my three years as chief economist of the World Bank, labor market issues were looked at through the lens of neoclassical economics. A standard message was to increase labor market flexibility. The not-so-subtle subtext was to lower wages and lay off unneeded workers.

Our economy has not served large fractions of our population. Trump grasped that. And rather than saying, "What have we not done right?" he said, "It's those foreigners. Let's build a wall." He says globalization is unfair to the United States.

It is trust, more than money, that makes the world go round.

There is a clear and strong link between the economy's present woes and the Iraq war. The war was at least one of the factors contributing to rising oil prices - which meant Americans were spending money on imported oil, rather than on things that would stimulate the american economy. Hiring Nepalese contractors in Iraq, moreover, doesn't stimulate the American economy in the way that building a school in America would do - and obviously doesn't have the long term benefits.

There is a growing consensus that the European systems have worked better than the American: They have been able to deliver better health care to more people at lower cost.
