A few hundred years ago, perhaps 85 or even 90 percent of humanity lived below a standard of living that today only 40 or 45 percent fail to reach. But at that earlier time only part of this poverty could have been eradicated, and this at substantial cost not only to the pleasures of the affluent, but also to their well-being and to human culture. In our time, nearly all severe poverty could be eradicated at a cost to the affluent that is truly trivial.

Whatever we, as prospective participants unaware of our specific features, would desire society to be like is what, morally speaking, we ought to institute.

Companies are actually much better than governments and other bureaucracies at organizing in a holistically efficient way the extremely complex path from the examination of molecules all the way to the delivery of medicines to patients. Already in the conception and selection of research projects, companies would anticipate all the challenges down the line that they will need to overcome in order to achieve actual health impact. Bureaucratic organizations, by contrast, are notoriously bad at this sort of optimizing.

Purchasing power parities are not a reasonable method for comparing households across countries or currencies. The reason for this is simply that PPPs are sensitive to the prices of all the commodities, goods and services, that households are consuming worldwide, with each commodity weighted in the calculations according to its share in international household consumption expenditure.

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.

I think that many citizens understand how our system works, or rather, fails to work, for structural reasons. But who has the capacity and the incentives to bring change? The banks and other corporations love the system because it allows them to buy legislation that serves their own interests even at the expense of the vast majority of citizens. Incumbent politicians love the system because it allows them to raise millions of dollars toward defending their seats.

We live in a world where economic positions - income and wealth - are very unevenly distributed, and this leads to the widespread persistence of poverty.
