This accumulated of centuries especially in Europe. I am absolutely not surprised Jews are at the top of the world now. And I think they deserve it. Even though most Jews I meet today don't care too much about Judaism, they do still have a very Jewish identity and self-perception and feel very connected to each othee/their 'people' and thus, would support each other.
