Paul Krugman: The Social Contract

This week President Obama said the obvious: that wealthy Americans, many of whom pay remarkably little in taxes, should bear part of the cost of reducing the long-run budget deficit. And Republicans like Representative Paul Ryan responded with shrieks of “class warfare.”

It was, of course, nothing of the sort. On the contrary, it’s people like Mr. Ryan, who want to exempt the very rich from bearing any of the burden of making our finances sustainable, who are waging class war.

As background, it helps to know what has been happening to incomes over the past three decades. 
Detailed estimates from the Congressional Budget Office — which only go up to 2005, but the basic picture surely hasn’t changed — show that between 1979 and 2005 the inflation-adjusted income of families in the middle of the income distribution rose 21 percent. That’s growth, but it’s slow, especially compared with the 100 percent rise in median income over a generation after World War II.
