There are 196 countries in the world. 25 of them are very rich, defined as having an average wealth per person of over $100,000 a year. But far more countries are quite poor, and some are very very poor. In the 20 poorest countries of the world, the per capita wealth is under a $1,000 a year, or under three dollars a day. Every country is now more or less on a path to growth, but the poor ones are growing very, very slowly. If Zimbabwe continues at its current growth rate, it will qualify as a ‘rich country’ in 2722 years.
