Economists have spent their lives attempting to evolve theories that would account for how salient features of reality might emerge if we did live in their ideal world, but since we don’t, their theoretical enterprise is of doubtful utility. It is like describing how one could bake a delicious wedding cake using only honey, bicarbonate of soda, and raw eggplant.
如果我们确实生活在理想王国里，经济学家可以不断提升他们的理论，试图解释我们生活中可能遇到的问题。遗憾的是我们不是生活在理想王国里，所以他们的理论体系存在问题。这就像一个人不可能仅仅使用蜂蜜，苏打水和茄子就可以烘烤出一个美味的婚礼蛋糕来那样。
