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.

People at the top spend less money than those at the bottom so when you have redistribution toward the top, aggregate demand goes down. Unless you intervene, you're going to have a weak economy unless something else happens. That something else could be a bubble. The United States tried a tech bubble and a housing bubble, but those were not sustainable answers. So I view inequality as a fundamental part of our macroeconomic weakness.

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?"

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.

Active learning is always involved with interaction between teachers and students and Socratic methods and that's gonna continue.

The protesters have called into question whether there is a real democracy. Real democracy is more than the right to vote once every two or four years. The choices have to be meaningful. But increasingly, and especially in the US, it seems that the political system is more akin to "one dollar one vote" than to "one person one vote". Rather than correcting the market failures, the political system was reinforcing them.

The national debt will have increased by approximately 50% in just eight years! We will have created a new unfunded entitlement - disability and health care benefits for the huge number of disabled veterans returning from the Iraq war.
