Macroeconomic policy can never be devoid of politics: it involves fundamental trade-offs and affects different groups differently.

The issue is: $1 trillion or $2 trillion is a lot of money. If our objective is to have stability in the Middle East, secure oil, or extend democracy, you can do a lot of democracy buying for this sum. To put it in context: The whole world spends $50 billion a year on foreign aid.

What Trump has announced - that he is going to not obey rules by which we govern our relations with other countries. He's going to reject the treaties that we have had in the past. He is going to go from what is called a multilateral system, where we all work together, to trying to deal country by country and basically throw out what has been achieved over a 60-year period.

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.

We noted the psychological problems facing many of the returning from Iraq veterans - of the 700,000 returning veterans, more than a 100,000 have been diagnosed with problems, but the numbers are likely to get worse, as those with multiple deployments return. We should have valued the loss of life as a result of these suicides, using the same procedures we used for the loss of those who died in combat.

I've always been sceptical about the notion that the market is a person you can engage in an argument with, and that that person is an intelligent, rational, well-intentioned person: it is fantasy. We know that ... the market is subject to irrational optimism and pessimism, and is vindictive ... You're dealing with a crazy man ... Having got what he wants he will still kill you.

The recovery of the banks is what happens when you reduce competition, lend money to them at zero interest rates, allow them to gamble. That particular style of restoration actually inhibits the economic recovery.
