White Collars Turn Blue
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.

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.
