It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phoney numbers about jobs created or lost.

Wealthy individuals bought themselves a radical right party, believing - correctly - that it would cut their taxes and remove regulations, but failed to realize that eventually the craziness would take on a life of its own, and that the monster they created would turn on its creators as well as the little people.

Rising inequality isn’t about who has the knowledge; it’s about who has the power.

There has been plenty to criticize about President Obama’s handling of the economy. Yet the overriding story of the past few years is not Mr. Obama’s mistakes but the scorched-earth opposition of Republicans, who have done everything they can to get in his way - and who now, having blocked the president’s policies, hope to win the White House by claiming that his policies have failed.

Something terrible has happened to the soul of the Republican Party. We've gone from bad economic doctrine. We've even gone beyond selfishness and special interests. At this point we're talking about a state of mind that takes positive glee in inflicting further suffering upon the already miserable.

We should try to create the society each of us would want if we didn't know in advance who we'd be.

Yes, over the centuries economic progress has reduced some gross disparities - modern Americans are relatively unlikely to simply starve to death (though it can happen), so in that sense the gap between rich and poor has narrowed. But the question isn't whether society is, in some sense, more equal than it was in 1900. It's whether it is radically more unequal than it was in 1970. And of course it is.
