In 1990 the region with the lowest wealth or Gross Domestic Product (GDP) was Central Africa. The GDP of Central Africa was 0.8% of the GDP of the richest region, North America. If just 1% of the North Americaís GDP had been redistributed to Central Africa the regionís GDP would have more than doubled.
Wealth per person had doubled since 1960, and the world GDP rose from PPP US$8 trillion to US$27 trillion over these thirty years. This vast increase in wealth was distributed in a broadly similar pattern to 30 years before. One change is the growth of Japan, China, the Republic of Korea and Taiwan.
