For decades, rapid economic growth has been the norm for developed countries. An educated workforce, a large population boom, major technological advances, and abundant fossil fuels were the key components of growth, generating substantial and broadly distributed increases in standards of living in many countries. We have grown so used to such growth that we inevitably view it as a panacea for a host of economic ills, whether it's a deep recession or income inequality.
We now understand, however, that the postwar growth paradigm is not environmentally sustainable. We also know that the shared prosperity it once delivered is itself unraveling. With these combined trends, something has to give in order to maintain living standards.
One possible scenario, with surprisingly good news for average Americans, is that constraints on growth will force political leaders to accept redistribution as a policy tool. Indeed, if we cannot grow our way to broadly shared prosperity again, redistribution is the only way to save the middle class.
