○ 질문내용 :Reliance on monetary statistics to convey well-being renders one liable to accept and even encourage destruction in order to increase production. The paradox was pointed out by French economist Frederic in his parable of the broken window. In the parable, Frederic describes a scene in which a boy break the window of a town shop. The crowd that gathers naturally pities the shopkeeper and admonishes the vandal. But almost instantly the crowd has a chage of heart. They realize that the broken glass means the shopkeeper must spend some six francs to have the window replaced. Six francs to the glazier means that business has been conducted where it would not have been otherwise.
