Paul Krugman: Is Vast Inequality Necessary?

How rich do we need the rich to be?

That’s not an idle question. It is, arguably, what U.S. politics are substantively about. Liberals want to raise taxes on high incomes and use the proceeds to strengthen the social safety net; conservatives want to do the reverse, claiming that tax-the-rich policies hurt everyone by reducing the incentives to create wealth.

Now, recent experience has not been kind to the conservative position. President Obama pushed through a substantial rise in top tax rates, and his health care reform was the biggest expansion of the welfare state since L.B.J. Conservatives confidently predicted disaster, just as they did when Bill Clinton raised taxes on the top 1 percent. Instead, Mr. Obama has ended up presiding over the best job growth since the 1990s. Is there, however, a longer-term case in favor of vast inequality?
