Book excerpt: Renowned economist and author of Big Business Tyler Cowen brings a groundbreaking analysis of capitalism, the job market, and the growing gap between the one percent and minimum wage workers in this follow-up to the New York Times bestseller The Great Stagnation. The United States continues to mint more millionaires and billionaires than any country ever. Yet, since the great recession, three quarters of the jobs created here pay only marginally more than minimum wage. Why is there growth only at the top and the bottom? Economist and bestselling author Tyler Cowen explains that high earners are taking ever more advantage of machine intelligence and achieving ever-better results. Meanwhile, nearly every business sector relies less and less on manual labor, and that means a steady, secure life somewhere in the middle—average—is over. In Average is Over, Cowen lays out how the new economy works and identifies what workers and entrepreneurs young and old must do to thrive in this radically new economic landscape.
