[T]he attempt to shift the discussion away from the short run is not, as often portrayed, an act of vision of courage. On the contrary, it’s an act of cowardice, an attempt to evade responsibility for a disastrous state of affairs that we could fix, but choose not to.But this long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again.
