On the contrary: whenever I see someone accuse a work of antisemitism because it has greedy bankers, I think that says a lot more about the accuser than it does the work in question. It is not normal to look at a fictional banker sect and assume that they are meant to be Jews, or a reflection on Jews.
Compared to those, all bankers of the world even combined are still a minor insignificant player. I wonder if we will ever see 'occupy sillicon valley' movement?
