The Great Stagnation: How America Ate All the Low-Hanging Fruit of Modern History, Got Sick, and Will (Eventually) Feel Better
Tyler Cowen, 2011

Quick read. Interesting comments on the idea that technological innovation has slowed, which has stagnated the U.S. economy since the 1970’s. Has the ring of truth to it. I would recommend it and I will read the follow-up, Average is Over: Powering America Beyond the Age of Stagnation, soon.
