Accounting for the Great Enrichment is the deepest puzzle of the social sciences. Some think it was all just a matter of figuring out how to exploit natural resources, or some combination of enslavement, exploitation, and colonial plunder, or maybe it was just geographic and genetic good luck. None of that really explains it.That's the starter. Here's the main course. Go, read, and understand.
Each of these views is part of the truth. The debate is mainly a matter of how beliefs and norms, institutions and incentives, scientific knowledge and technical innovation all fit together. Which are the causes and which are the effects? There’s no way to adequately summarize the involuted nuance of the debate. But it’s not wrong to sum it up bluntly like this: humans rather suddenly got immensely better at cooperating and now a lot of us are really rich.Emergence is messy. But mutation, selection, and adaptation don't lend themselves to easy management.
Before I go on, I hasten to add that not all of us are really rich. Most humans don’t live in the places first touched by the Great Enrichment and aren’t that rich now. Moreover, the path from “extractive” to “inclusive” institutions in the places that did get rich has been bumpy and brutal, and the liberal revaluation of values has always been opportunistically applied and rife with hypocrisy.
