It's actually a tribute to the quality of economics teaching that they have persuaded so many generations of students to believe in so much that seems so counter to what the world is like. Many of the things that I'm going to describe make so much more common sense than these notions that seem counter to what one's eyes see every day.

For instance, one of the costs of the war is that soldiers today get very seriously injured but stay alive, and we can keep them alive but at an enormous price.

Policies seemed almost deliberately designed to suppress new enterprise and job creation. How many Americans will start a business if the interest rates are 150 percent?

In the early 1990s, there was a debate among economists over shock therapy versus a gradualism strategy for Russia. The people in Russia who believed in shock therapy were Bolsheviks a few people at the top that rammed it down everybody's throat. They viewed the democratic process as a real impediment to reform.

The momentum today behind the idea of a new global reserve currency reflects, in effect, the rise of the rest in world politics and economics, led by China.

China's accumulation of reserves is a result of the IMF's mismanagement of the Asian financial crisis a decade or so ago. If countries know they can't rely on the IMF to help them, their best defense is their own reserve cushion. In a time of spreading global recession, too much emphasis on savings in surplus countries like China can impede prospects for global growth.

What most Americans mean when they say "the end of the recession" is, "When will it be back to normal? When can we get jobs? When will the employment rate be back to 4 percent or 5 percent?"
