The powershift began already several years ago, under the Bush administration, when the dollar became very volatile and started declining. That is when China shifted from having almost 100 percent of its reserves in dollars to 75 percent. Some countries went completely out of the dollar. The dollar, for all intents and purposes, lost its special reserve status and people starting talking about a portfolio, or basket, approach as a store of wealth instead of the dollar.

Similarly, payments for a dead soldier amount to only $500,000, which is far less than standard estimates of the lifetime economic cost of a death. This statistical value of a life in the US amounts to circa $6.5 million.

Development is about transforming the lives of people, not just transforming economies.

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.

I knew that discrimination existed, even though there were many individuals who were not prejudiced.

Certainly, the poverty, the discrimination, the episodic unemployment could not but strike an inquiring youngster: why did these exist, and what could we do about them.

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.
