Serious growth happened only after 1800, at first in northwestern Europe, 2% per capita in PPP [purchasing power parity] conventionally adjusted for inflation, as in the USA 1800–present, and now the world. Its magnitude is enormous, the Great Enrichment. It was a rise from $2 or $3 a day to over $100, a factor of 30. (I recently had to explain to a justly famous anthropologist that [(30–1) / 1] x 100 is 2,900%, or about 3,000%. He said that he could believe a factor of 30 … but not 3,000%.)
The exactitude, of course, is inessential. In Japan and Finland it was roughly the factor of 30. But it could be the worldwide factor since 1800 of 10 only, about $2 or $3 to $30 a day (to $10,000 a year, the level of Brazil now, to fix ideas), and still be utterly novel. As a Brit might say, the Great Enrichment was gobsmacking.
The enrichment was actually much greater than the factor of 30, because price indices, especially recently, do not adequately reflect improvements in quality, as was determined in the early 1990s by the Boskin Commission … Consider your cell phone, your auto tires, your medical treatment — all greatly better, recently. Even economic facts and analyses are better. (Well, sometimes.) The downward bias from inadequately deflating money prices for improved quality is not far from 2% per year, which would double recent growth rates in the rich countries.
Its magnitude, novelty, recency, and location are all crucial to explaining the Great Enrichment, because together they strongly suggest that there was something deeply peculiar about Britain in the 18th century, and that afterwards the peculiarity spread to the rest of the world. Such facts make “run-up” theories such as in Stephen Broadberry et alii look implausible, because they depend on a metaphor of an airplane taking off, with little else by way of explanation for why the Industrial Revolution (a factor of 2) happened or, especially, its follow-on the Great Enrichment (a factor of 20 or 30). Likewise, it is dubious to attach the Great Enrichment to remote causes within Europe, such as the Black Death — which originated in China, with similar terrors, and yet yielded no Great Enrichment there. Also dubious is the Eurocentric belief, prominent in conservative circles, of some ancient superiority of melanin-challenged Volk back in the Black Forest. (Did you know, for example, that all European countries had common law in the Middle Ages, that is, judge-found-and-made, not legislated or codified?)
The Great Enrichment is the second most important secular event in human history, second only to the domestication of plants and animals making for cities and literacy.
