Unfortunately Jewish history tells us that whenever mobs of people gather to protest “bankers” they are this || close to turning into an anti-Jewish hate fest. It is just a fact of historic record. Jews with any sense of their history probably cringe at the OWS movement. People like this woman only serve to validate those fears. It brings them out.
This is not to say criticism of banks, banking practices, or the Federal Reserve is anti-Semitic. Criticizing ideas and practices is fine and good. It is better when you have solutions, but criticism is fair. And people are free to hate. But people who willingly, knowingly and deliberately associate themselves with hateful people will come to be known as hateful people themselves.
Yes, equating "bankers" with "Jews" stems historically from medieval and Renaissance Europe, where Jews were instrumental in creating what became modern banking. (Those Jews were filling a societal need, as Christians were banned by the Catholic Church's prohibition of usury.) So bankers evolved into a popular stereotype of Jews among antisemites.
In the United States historically, though, Jews have had very little participation in the banking industry until relatively recently.
