What's behind that "rapid decline in poverty, illiteracy and disease"?

Nick Kristof completely omits the lede (Cato):

The Homo sapiens has been on this earth for 200,000 years. For 99.9% of that time, we lived in ignorance, poverty and misery. What has changed? Reading the NYT, the reader is left with the impression that “good stuff,” like manna from heaven, suddenly was conjured up out of thin air.

Not so. The key to the improvements in the lives of ordinary people over the last 200 years were industrialization and trade, which generated historically unprecedented rates of growth. And the importance of growth cannot be overemphasized. There is not a single example of a country emerging from widespread poverty without sustained economic growth. As University of Oxford Professor Paul Collier writes, “Growth is not a cure-all, but lack of growth is a kill-all.”

It reminds me of Robert Heinlein's quote:

Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded — here and there, now and then — are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty.

This is known as "bad luck.
