An explanation of those contrasts invokes branching chains of cause and effect. Both the countries of North America (the United States and Canada) are twice as rich as the next richest New World country (Barbados), and some 20 times richer than the poorest (Haiti). The actual numbers are US$37,562, $30,677, $15,720 and $1,742, respectively1, expressed here as annual per capita gross domestic product (GDP) corrected for differences in purchasing power. Why are these differences so vast, and can an understanding of the causes help the plight of the poor New World countries? The answers are much debated by social scientists and policy-makers.
