Thanks to economists, all of us, from the days of Adam Smith and before right down to the present, tariffs are perhaps one tenth of one percent lower than they otherwise would have been. And because of our efforts, we have earned our salaries ten-thousand fold.

We economists don't know much, but we do know how to create a shortage. If you want to create a shortage of tomatoes, for example, just pass a law that retailers can't sell tomatoes for more than two cents per pound. Instantly you'll have a tomato shortage. It's the same with oil or gas.
