The World Bank is the monopoly provider of poverty data and, partly due to a leadership change there, the World Bank's reporting has been heavily on the rosy side since about 2000. The Bank's cultivation of an upbeat picture affords a very interesting lesson in statistics and how you can, depending on which numbers you present and how you present them, create a more positive or more negative impression of the evolution of poverty.

Ordinary people like you and me can achieve very little on their own. We need to build support. Even if you are a thought leader and have some good ideas on how to make the world better, and even if you write five or ten books - that won't have much effect unless you have people who are willing to support your ideas.

Because present procedures by design favor the affluent, the poor are being increasingly marginalized. And because the poor are so marginalized, they can exert little influence on institutional design decisions. We need to break out of this vicious spiral and create momentum in the opposite direction.

What is really nice about the Health Impact Fund is that it is a win-win, something that without much cost to anyone makes a lot of people better off.

In order to achieve something, in competition with the powerful and smartly wielded influence of corporations, we need to join forces and be as well-organized as they are. This does not come natural to us more intellectual types, as we tend to be averse to hierarchy and groupthink; we don't like to be part of anything like a disciplined and well-organized team or movement. But the alternative is to continue losing politically - which means continued failure to protect the world's poor, who are really bearing the brunt of our disorganization.

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.

Our international banking system allows banks to accept funds gained from tax evasion and other crimes and thereby facilitates and encourages embezzlement by public officials, especially in developing countries, as well as tax evasion and tax avoidance by multinational corporations.
