I suspect that historians one day will view last month’s Fed announcement as the catalyst for a similar change in conventional wisdom – both in America and around the world. They will conclude that two factors motivated Bernanke: persistently high US unemployment – which, like the inflation problem that Volcker faced, risks becoming deeply embedded in the structure of the economy – and virtual paralysis on the part of other policymaking agencies.
我怀疑有一天历史学家会把上个月的美联储公告视为促成美国和全世界传统智慧发生类似转变的催化因素。他们可能总结出有两项因素促使伯南克这么做：一是美国失业率持续高企——与沃尔克面临的通胀问题类似，它也有可能深深嵌入经济结构——二是其他决策机构在实质上陷入瘫痪。
