What happened after 9/11 - and I think even people on the right know this, whether they admit it or not - was deeply shameful. The atrocity should have been a unifying event, but instead it became a wedge issue. Fake heroes like Bernie Kerik, Rudy Giuliani, and, yes, George W. Bush raced to cash in on the horror. And then the attack was used to justify an unrelated war the neocons wanted to fight, for all the wrong reasons....The memory of 9/11 has been irrevocably poisoned; it has become an occasion for shame. And in its heart, the nation knows it.

Economics is not a morality play.

I've always believed in expansionary monetary policy and if necessary fiscal policy when the economy is depressed.

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.

Unsustainable situations usually go on longer than most economists think possible. But they always end, and when they do, it's often painful.

Now, it’s true that some of the protesters are oddly dressed or have silly-sounding slogans, which is inevitable given the open character of the events. But so what? I, at least, am a lot more offended by the sight of exquisitely tailored plutocrats, who owe their continued wealth to government guarantees, whining that President Obama has said mean things about them than I am by the sight of ragtag young people denouncing consumerism.

The key reason executives are paid so much now is that they appoint the members of the corporate board that determines their compensation and control many of the perks that board members count on. So it's not the invisible hand of the market that leads to those monumental executive incomes; it's the invisible handshake in the boardroom.
