The Economist has an interesting article that compares poor in Africa to poor in America.
Why juxtapose the lives of a poor man in a rich country and a relatively well-off man in a poor one? The exercise is useful for two reasons. First, it puts the rich world’s wealth into context. A Congolese doctor, a man most other Congolese would consider wealthy, is worse off materially than most poor people in America. That, in itself, is striking.
