Now it is unambiguously clear that trickle-down economics does not work. But what does that mean? That means we have to structure our economic policies to make sure that we have shared prosperity. And you don't do that by giving a tax cut to the big winners and raising taxes on those who have not done very well. Your economic policy has to respond to the way our economic system has been working.

There was a hope then by some people that what we call trickle-down economics would work. That if you made the economy pie bigger, everybody would benefit. Twenty-five years after NAFTA, we know that that is not true. We should have known then that it was not true.

I think what they've been doing is largely almost in firefighting mode without a good conceptual framework - either at the micro or the macro level. Micro, you would ask: "What kind of financial or banking system do we want?" Macro, you would say: "What are the underlying problems in the structure of our economy?"

Anybody who has watched government from the inside recognizes that governments need institutions, need ways to respond to crises.

The proposal for a new global reserve currency - or Special Drawing Rights - is a good idea for many reasons. Yes, for the Chinese it would cushion any fall in the value of the dollar per se because it would only be part of a basket of other currencies, including the yen and the euro.

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.

I'm writing from New Zealand - a country that decided from the beginning that the War was wrong, and chose not to participate in Iraq War.
