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 then can only tell us that when the storm is long past the ocean is flat again. (但是长远效应是一种误导。长远来看我们都死了。经济学家总是把自己看得太轻松与无用。如同风暴降临时,只能告诉大家“等风暴过去后,大海又会风平浪静的”) ——约翰 梅纳德 凯恩斯.
