Over the period from 1988 to 2005, the income share of the top five percent has grown by about 3.5 percent of global household income, and the shares of all the other groups have diminished. The greatest relative reduction was in the bottom quarter, which lost about one third of its share of global household income, declining from 1.155 to 0.775 percent, and now is even more marginalized.

Though people could, in principle, cross national borders to reach places where their work is more highly rewarded, they are in fact prevented from doing so. As a result, huge differences also persist in the price of labor, as you can see when you get a haircut in rural India or hire a driver or babysitter in Bolivia. You can easily buy such services at one-fiftieth the price you would pay in London, Hamburg or Manhattan.

Some of the developing-country governments and populations are tired of having things rammed down their throats, but we're not yet at the stage we want to get to, namely where the developing countries join forces with one another on behalf of creative alternative ideas about how to take things forward.

Countries compete in offering easy working conditions to their banks. In many jurisdictions, you can deposit money anonymously with no questions asked, even if the accepting bank knows that it derives from criminal activities.

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

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.

It is irrational to charge high prices for socially valuable innovations as this guarantees that they will be underutilized. It is much better to sell them at cost and then to reward the innovator in some other way. This is not always possible, because in some cases the value of an innovation is in the eye of the beholder; it's very difficult to value how much a new Madonna song is worth, for example. But in the case of medicines, green technologies and seeds in agriculture, such an alternative reward mechanism is fairly straightforward.
