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.

China's accumulation of reserves is a result of the IMF's mismanagement of the Asian financial crisis a decade or so ago. If countries know they can't rely on the IMF to help them, their best defense is their own reserve cushion. In a time of spreading global recession, too much emphasis on savings in surplus countries like China can impede prospects for global growth.

The fact that the government had to put up hundreds of billions of dollars to Citibank in guarantees was a public declaration that Citibank was a mess. Making Citibank go through financial restructuring would not have conveyed any more different information. So it's very hard to see why it would have had that kind of a panic if it were done well.

It is unlikely that others would even demand their money back overnight, for doing so would lead to the value of the dollar plummeting; what they would get back with be worth little. But what we are already seeing is an erosion of confidence of the dollar, which is seeing the dollar fall in value.

Countries were told they had no incentives because of social ownership. The solution was privatization and profit, profit, profit. Privatization would replace inefficient state ownership, and the profit system plus the huge defense cutbacks would let them take existing resources and an increase in consumption. Worries about distribution and competition or even concerns about democratic processes being undermined by excessive concentration of wealth could be addressed later.

I don't think if we had been able to make that choice rationally, we would have said that's what we want to do. We would have said: "Can't we save the banks and solve our health care problems?" The answer is yes. You could have.

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.
