On February 3, Federal Reserve Chair Janet Yellen, the first woman to lead the central bank and likely the most qualified nominee ever for the post, will exit the Fed, leaving a legacy described as “near perfection” and with an “A” grade from a majority of economists. And yet in 2014, the US Senate confirmed Yellen by a vote of 56-26, the lowest number of “yes” votes a confirmed Fed chair has ever received. The economy under Yellen hasn’t been flawless — wage growth and inflation have remained sluggish — but generally, she’s done her job exceptionally well.
