Most people, if pressed on the subject, would probably agree that extreme income inequality is a bad thing, although a fair number of conservatives believe that the whole subject of income distribution should be banned from public discourse. (Rick Santorum, the former senator and presidential candidate, wants to ban the term “middle class,” which he says is “class-envy, leftist language.” Who knew?) But what can be done about it? The standard answer in American politics is, “Not much.” Almost 40 years ago Arthur Okun, chief economic adviser to President Lyndon Johnson, published a classic book titled “Equality and Efficiency: The Big Tradeoff,” arguing that redistributing income from the rich to the poor takes a toll on economic growth. Okun’s book set the terms for almost all the debate that followed: liberals might argue that the efficiency costs of redistribution were small, while conservatives argued that they were large, but everybody knew that doing anything to reduce inequality would have at least some negative impact on G.D.P. But it appears that what everyone knew isn’t true. Taking action to reduce the extreme inequality of 21st-century America would probably increase, not reduce, economic growth. Let’s start with the evidence.
