The world has made great progress in eradicating extreme poverty

TO PEOPLE who believe that the world used to be a better place, and especially to those who argue that globalisation has done more economic harm than good, there is a simple, powerful riposte: chart 1, below. In 1981 some 42% of the world’s population were extremely poor, according to the World Bank. They were not just poorer than a large majority of their compatriots, as many rich countries define poverty among their own citizens today, but absolutely destitute. At best, they had barely enough money to eat and pay for necessities like clothes. At worst, they starved.
