The rates of long-run economic growth and capital transfer from developed to underdeveloped areas

The underdeveloped areas, which hold at least two-thirds of the entire population of the world, produce now only about one-seventh of the world’s gross output of goods and services; moreover, their rate of economic growth is at the present time much lower—possibly only half as high—as that of the advanced industrialized countries. That means that the contrast between the richer and the poorer areas tends to increase rather than diminish.
