I think one big improvement would be if we somehow made it cheaper and easier for developing countries to learn from the sad experience of some of the developed countries, and also from some of the positive experiences we have of building good transportation systems, like high-speed rail.

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.

This splendid book discusses how, in the last two hundred fifty years, large numbers of people have achieved levels of well-being that were previously available only to a few individuals, and how this achievement has given rise to equally unprecedented inequalities. Unique in its focus and scope, exceptional knowledge and coherence, and careful argumentation, The Great Escape is highly illuminating and a delight to read.

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.

Dictatorial regimes often manage to keep themselves in power because they are recognized by foreigners as representing the state and its people, and therefore as entitled to sell the country's natural resources and to borrow money in its people's name. These privileges conferred by foreigners keep autocrats in power despite the fact that they were not elected and do not rule in the interest of the population.

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.
