Temporary nationalization of the banks that are in very bad shape would mean basically that the government is the temporary owner. I always believe that the government should focus on its comparative advantages, and banking is not one of them. It should, therefore, if it nationalizes banks, sell them back to the private sector.

The IMF insisted that both Russia and Brazil maintain their currency at over-valued levels. Who are you protecting when you try to maintain that exchange rate by having high interest rates? You're protecting domestic and foreign firms that have gambled on the exchange rate. And who is paying the price? The small businesses that did not gamble [and no longer can afford loans], the workers who are going to be put out of jobs.

The war in Iraq has been very, very expensive - partly because the Administration tried to keep the apparent costs down. But the benefits have been elusive at best - partly because the ostensible reasons for going war were unconnected with reality - no weapons of mass destruction, no connections with 9/11.

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.

We could have saved Wall Street without putting our future in jeopardy. I predicted that there would be all-around consequences - in the long run as well as in the short run. People are now saying we can't afford health care reform because we spent all the money on the banks. So, in effect, we're saying that it's better that we give rich bankers a couple of trillion than giving ordinary Americans access to health care.

The crisis was 2008, in 2015 - almost eight years later and the gap between where we would have been and where we are is huge and not closing. The implied unemployment rate is very high, labour force participation is very low, and the increase in wages in the second quarter was the lowest in 25 years. Before this turmoil, the U.S. economy was in better shape than Europe or Canada, but not strong.

If the President asked you to help, I don't think anybody could refuse, unless one felt that one couldn't be effective.
