[T]his big engine that determines how much food is grown, whether you’ll have to sell your kidneys to feed your family, whether the factory down the road will make Zeppelins, whether the restaurant on the corner can afford the coffee beans, all this important stuff has *no one in charge of it*. It is a runaway train, the driver dead at the switch, the passengers clinging on for dear life as their possessions go flying off the freight-cars and out the windows, and each curve in the tracks threatens to take it off the rails altogether.

There is a small number of people in the back of the train who fiercely argue about when it will go off the rails, and whether the driver is really dead, and whether the train can be slowed down by everyone just calming down and acting as though everything was all right. These people are the economists, and some of the first-class passengers pay them very well for their predictions about whether the train is doing all right and which side of the car they should lean into to prevent their hats from falling off on the next corner.

Everyone else ignores them.
