You may know that in India now the Tata car is becoming all the rage; you can buy it for one lakh - $2000 dollars - it's very, very cheap. So India seems to be going the route that China went a few years ago and that developing countries all over the world seem to want to follow, namely, to rely on these personal vehicles, which is just an irrational way of organizing transport.

The bottom quarter of the human population has only three-quarters of one percent of global household income, about one thirty-second of the average income in the world, whereas the people in the top five percent have nine times the average income. So the ratio between the averages in the top five percent and the bottom quarter is somewhere around 300 to one - a huge inequality that also gives you a sense of how easily poverty could be avoided.

To make a proper moral appraisal of the prevalence of severe poverty today, we should focus not on comparisons with times past, when the global average income was much lower, but on a comparison with what would be possible in our time, given the current global average income and level of technological and administrative development.

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.

If you ask yourself who is paying for pharmaceutical innovation today, the answer is that it's the more affluent populations paying for still-patented advanced medicines at the pharmacy, for comprehensive insurance coverage or for a national health system.

There is at the global level a very small number of actors who can meaningfully weigh in on global institutional design, who are able - through powerful governments and most effectively through the government of the United States - to exert substantial influence on international negotiations, which are routinely conducted behind closed doors.

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.
