AN insidious trend has developed over this past third of a century. A country that experienced shared growth after World War II began to tear apart, so much so that when the Great Recession hit in late 2007, one could no longer ignore the fissures that had come to define the American economic landscape. How did this “shining city on a hill” become the advanced country with the greatest level of inequality?
One stream of the extraordinary discussion set in motion by Thomas Piketty’s timely, important book, “Capital in the Twenty-First Century,” has settled on the idea that violent extremes of wealth and income are inherent to capitalism. In this scheme, we should view the decades after World War II — a period of rapidly falling inequality — as an aberration.
