Our maladies are largely random, and even if our doctors cannot tell us which ones we will have in the next year, or eliminate all of our suffering when we have them, we are happy for the help that they can provide. Likewise, most economists devote their efforts to issues far removed from establishing a consensus outlook for the stock market or the unemployment rate.
但如此批评并不公平。我们不会指责医生没有预见到所有疾病。我们的发病大部分是随机的，即使我们的医生无法告诉我们未来几年我们会得什么病，或者无法在我们得病时消除我们的所有痛苦，但我们仍乐于接受他们所能提供的帮助。类似地，大部分经经济学家致力于问题，而不是构建对股市或失业率前景的共识。我们应该感谢他们的工作。
