World War II was really unusual, because America was in the Great Depression before. So the war did help the US economy to get securely out of this decline. This time, the war [in Iraq] is bad for the economy in both the short and long run. We could have spent trillions in research or education instead. This would have led to future productivity increases.

The Bush administration has been doing everything it can to hide the huge number of returning veterans who are severely wounded - 17,000 so far including roughly 20 percent with serious brain and head injuries. Even the estimate of $500 billion ignores the lifetime disability and healthcare costs that taxpayers will have to spend for years to come.

I went to Amherst because my brother had gone there before me, and he went there because his guidance counselor thought that we would do better there than at a large university like Harvard.

Trickle-down economics is a myth. Enriching corporations - as the TPP would - will not necessarily help those in the middle, let alone those at the bottom.

For 60 years, since World War II, we have been trying to create a rules-based system, a global economic system. We understand that what makes our economy function is what we call the rule of law, and what is true domestically is also true internationally. It is important to have rules by which we govern our relations with other countries.

Negative effects on the economy were covered up with a flood of liquidity from the Fed. That,plus lax regulation, led to a housing bubble, a consumption boom - but we were living on borrowed money. It was inevitable that there would be a day of reckoning, and it has now come. We will be paying the costs "with interest".

The striking thing about America is - it's historically, extraordinary unusual, I don't of any other instance - is that productivity of workers and wages have not moved in tandem.
