I lost all respect for odolvlovo with his comment ^^^^
Since you obviously know more and better than Yellen, why aren't you running the Fed?
+1. I was skeptical of Yellen, but she has said a few things that make me tentatively respect her. Also, though we might disagree on certain things, she came to her point of view through a lot of experience and knowledge. Might she be wrong? Absolutely. That being said we should consider what she has to say carefully.
My main problem with her is that she continues to cite the CPI as a measure of inflation, which I do not believe is accurate.
