For the United States, our political system is clearly distorted. We have gerrymandering so that there is a situation where a million more voters who vote for Democrats, yet the House is controlled by the Republicans. So clearly, the way our Congress operates is important. The other big issue is the influence of money in politics. It's not only campaign contributions. People like Trump - either you become very dependent on your benefactors or you are very rich.

The attempt to minimize cost and maximize profits often interfered with our true mission in Iraq. We should have been working to get jobs for Iraqis, but the contractors found it cheaper to import Nepalese and others. This increased resentment, contributed to unemployment, and to our losing the hearts and minds of the Iraqis.

They [free market policies] were never based on solid empirical and theoretical foundations, and even as many of these policies were being pushed, academic economists were explaining the limitations of markets for instance, whenever information is imperfect, which is to say always.

I trace the inequality to a particular set of decisions that we took when we lowered the tax rate from 91% down to very low levels at the top, where we stripped away regulations. So the result of that was not a more dynamic economy, but a more unequal society. We tried the experiment of trickle-down. A third of a century later, we can say fairly definitively that it was a failure.

The basic thing that made Trump popular is that he blamed others for the problems that we have in the United States. We have a problem. Let's face it. The typical income, median income, of a full-time male worker - and the workers who have a full-time job are the lucky ones - is at the same level it was 42 years ago. At the bottom, real wages in the United States are at the same level they were 60 years ago.

Unfettered market American-style capitalism doesn't work. Developing countries can't afford that kind of luxury. They just can't afford it. Period. If there's a mistake, they can't afford to put out $2 trillion.

My teachers helped guide and motivate me; but the responsibility of learning was left with me, an approach to learning which was later reinforced by my experiences at Amherst.
