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.

The problem with NAFTA was with what we wanted. And there, the agenda had been set by our corporations. So what is true is that workers in the United States and workers in the developing countries were often disadvantaged. They were worse off. The big winners were our corporations.

The country has large unfunded liabilities - social security, health care, and there will have to be some adjustments to these problems. What is scary though is how much worse things have gotten in the last eight years, and the Iraq war is one of the main factors.

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.

I often felt myself the lone voice in discussions suggesting that basic democratic principles be followed. I recommended that not only should workers' voices be heard, but they should actually have a seat at the table. You have the old boys' club discussing how the old boys' club should be reformed.

One has to always ask the question: Where can one be most effective in helping shape policies? It is always difficult when you're inside because you're very constrained.

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