Well let's put it this way. For a more powerful woman to come about, she would have to become President of the United States. The Fed has been around for 100 years and this is the first woman to chair it. It's big day for women everywhere!
Her name is Janet Yellen and I personally don't like her fiscal policy, but that's irrespective of her gender. If you don't know anything about her, do yourself a favor and google her.
