Like all gangster organizations, it's always preferable to hire family members or blood relations.

I think the ones who go above them are also Jewish, but are not exactly peasantry Jews. For example The Rothschilds and all the bigger families are Jewish but they share their power and are secondary to the religious power represented by the Sanhedrin council. The Talmud is in a way satanic, this is why people mistake the top of the pyramid with satanism and not Judaism.

The first 2 Jewish settlements in Palestine and much of the land purchase in Palestine was by the Rothschilds: https://sursockhouse.com/rothschild-land-purchases-and-early-israel/

So the bigger Jewish families are surely not just reputation with no power.
