A century ago, roughly one-third of U.S. workers toiled in agriculture. Now just 1.5% do. Yet agricultural output has skyrocketed, and the United States, after feeding itself, has plenty of food left over to export.
That explosion in agricultural productivity is considered a crowning achievement of 20th-century capitalism. Yet a similar trend that may now be underway in manufacturing and even the service economy isn’t viewed with the same reverential awe. Instead, the rise of robots and computers in place of workers looms as one of the great challenges in capitalism’s next century.
