It would be difficult for the Fed to respond differently if the financial sector gets into trouble again. But it does not have to maintain ultra-low interest rates after the crisis has passed, especially if those rates have little impact on generating sustainable economic activity.
倘若金融部门再度惹祸上身的话，估计美联储的做法还会是老一套。但它没必要在危机过后继续维持极低利率，尤其是当这些利率对促进可持续经济活动的作用已经很小的时候。这种做法仅仅是便宜了那些曾经过度放肆的银行——还有那些避税的富人。
