People know Krugman these days as a feisty political polemicist, but back when he was less politically engaged he was absolutely one of the very finest popularizers of economic ideas ever. This piece is a wonderful, brief introduction to the fundamental economic forces driving the world and a lot of my current thinking is preoccupied with the questions it raises. Reading it again, I realized that a point I like to make about the elevator being a great mass transit technology is almost certainly something I subconsciously picked up here.
