The proposal for a new global reserve currency - or Special Drawing Rights - is a good idea for many reasons. Yes, for the Chinese it would cushion any fall in the value of the dollar per se because it would only be part of a basket of other currencies, including the yen and the euro.

Wall Street banks have used the same tactic that Bush used in the war on terror - fear - and they've basically said that if you don't do what we tell you, the sky will fall. If you don't do what we tell you, it will be the end of capitalism as we know it. The failure of Lehman Brothers lent some credence to those fears.

The national debt will have increased by approximately 50% in just eight years! We will have created a new unfunded entitlement - disability and health care benefits for the huge number of disabled veterans returning from the Iraq war.

Health care is very different from other sectors of the economy in several respects, one of which is the fact that the risk can be very high beyond people's ability. That leads to insurance.

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.

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.

I think that for the developing world there are many versions of capitalism, and countries have to choose one that's appropriate.
