There will come a moment when the most urgent threats posed by the credit crisis have eased and the larger task before us will be to chart a direction for the economic steps ahead. This will be a dangerous moment. Behind the debates over future policy is a debate over history-a debate over the causes of our current situation. The battle for the past will determine the battle for the present. So it's crucial to get the history straight.

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 top 1 percent have the best houses, the best educations, the best doctors, and the best lifestyles, but there is one thing that money doesn't seem to have bought: an understanding that their fate is bound up with how the other 99 percent live. Throughout history, this is something that the top 1 percent eventually do learn. Too late.

I think in part the reason is that seeing an economy that is, in many ways, quite different from the one grows up in, helps crystallize issues: in one's own environment, one takes too much for granted, without asking why things are the way they are.

When you think of policies that are going to address inequality of wealth, you have to be very thoughtful about what economists call "incidence of taxes." If most of the savings is being done by capitalists, and you tax the return on capital, then they will have less to invest. That would mean, over the long run, that the rate of interest would go up. That would therefore undo some of the intent to lower the income of capitalists.

The extra curricular activity in which I was most engaged - debating - helped shape my interests in public policy.
