Jonathan Rauch writes: At a salon dinner in Washington recently, the subject was inequality. An economist took the floor. Economic inequality, he said, is not a problem. Poverty is a problem, certainly. Unemployment, yes. Slow growth, yes. But he had never yet seen a good reason to believe that inequality, as such—the widening gap between top and bottom, as distinct from poverty or stagnation—is harmful to the economy.
Perhaps he spoke too soon.
Once in a while, a new economic narrative gives renewed strength to an old political ideology. Two generations ago, supply-side economics transformed conservatism’s case against big government from a merely ideological claim to an economic one. After decades in which Keynesians had dismissed conservatism as an economic dead end (“Hooverism”), supply-siders turned the tables.

Something potentially analogous is stirring among the Left. An emerging view holds that inequality has reached levels that are damaging not only to liberals’ sense of justice but to the economy’s stability and growth. If this narrative catches on, it could give the egalitarian Left new purchase in the national economic debate.
“Widely unequal societies do not function efficiently, and their economies are neither stable nor sustainable in the long term,” Joseph E.
