After explaining the real difference between the New Yorker and Yanamamo tribes, economist Eric Beinhocker summarizes 2.5 million years of economic history on pages 9-11 of ‘The Origin of Wealth’ —
The lifestyle of the Yanamamo is fairly typical of our ancestors circa 15,000 years ago. This sounds like a long time ago, but in terms of the total economic history of our species, the world of the Yanamamo is the very, very recent past. If we use the appearance of the first tools as our starting point, it took about 2,485,000 years, or 99.4 percent, of our economic history to go from the first tools to the hunter-gatherer level of economic and social sophistication typified by the Yanamamo. It then took only (15,000 years, or) 0.6 percent of human history to leap from the $90, 102 SKU economy of the Yanamamo to the $36,000 per capita 1010 SKU economy of the New Yorkers.
