mr. farzad, anything in that?i am struck by going back to the time of alan greenspan -- i wish there was a way that fed chair could level with us and not talk in this highly scripted way. but i understand why that's done. you don't want to give anybody in the bond or stock market advance warning about how or if he is going to telegraph more hawkishness. i think it speaks to how problematic it is, the federal reserve right now, not only controls short-term interest rates but he is out there buying tens of billions of dollars of bonds every month to further keep rates down, to keep the mortgage markets stoked, to keep the corporate bond market quiet. this is problematic in that you want the economy to keep humming but you also don't want to stoke the inflationary embers and moreover in risk markets, this is a question we had going back to the time of alan greenspan and his predecessors. it visited every fed chair in the modern era, is you can keep federates at an emergency low rate for an extended period of time and
