Poverty persists, essentially, because the people at the bottom - the bottom quarter and also the bottom half - see the gains from the rising global average income wiped out by severe declines in their relative share.

It seems far-fetched, even preposterous, to blame the global economic order for the persistence of severe poverty in countries that are ruled by obvious thugs and crooks.

In the United States there are only two exceptions: banks have to report deposits they suspect to be related to either terrorism or drug trafficking. But if your funds derive from trafficking women and children for sexual exploitation, for example, or from illegal arms trafficking or any other illegal activity, then banks in the US are legally free to accept your money and are not required to report your deposit to the authorities.

If the Health Impact Fund were to be instituted, a single company would be in charge of a medical product all the way from its conception to the health improvements realized by actual patients. The company would be paid for health impact, and it would have to arrange the entire pipeline in between - all the steps of invention, of clinical testing, of getting marketing approval in many different countries, of wholesalers and retailers and prescriptions and so on - in a holistically optimal way.

Feudalism is an economic system where a few people own all the land and the others have no option but to be serfs on such a feudal estate. We now condemn feudalism. We condemn not merely the feudal lords but we condemn the whole structure of rules that sustained feudalism. I am asking people to think similarly about the world economy.

By using general consumption PPPs, the World Bank is, in effect, saying to the poor: "Sure, you cannot buy as much food as the dollar value we attribute to your income would buy in the United States. But then you can buy much more by way of services than you could buy with this PPP equivalent in the United States." But what consolation is this? The poor do not buy services - they are services, on their luckier days.

In order to prepare for meaningful change, we have to look at both sides of the problem. We need to examine the output of our political system, which is often very hostile to the poor abroad and hostile also to the poor and middle class domestically. And we must also look at the procedures through which this output is produced.
