Chapter 8 opens the agricultural section of the book, and it starts with a fact that surprised me: agriculture is tiny as a share of GDP in rich countries (about 1.3% in the U.S.) but massive in frontier economies, where it can be 40% or more of national output. Sierra Leone, Chad, Ethiopia. The U.S. still runs a trade surplus in farm goods, exporting billions more than it imports each year. So the sector matters globally even when it looks small on a developed-country balance sheet.
