Since the subject has come up, I will state my opinion on the subject.
The Jews do not run everything. It is widely believed, and by no one more than the Jews themselves, that they are secretly running things. Left wing paranoids are convinced that a cabal of right wing Jews (the “neoconservatives”) are in charge; right wing paranoids are convinced a cabal of left wing Jews are in charge.
There is indeed a group of people who run things, but they are not Jews. The easiest way to describe them from a cultural or religious standpoint would be “Episcopalians”, although “high church Calvinists” would be more accurate. Although these people don’t attend Episcopalian or Presbyterian churches, their grandparents mostly did. Quakers would also fall into this category.
While Jews are theologically more like Catholics (personal behavior is what God wants, thus the guilt thing) they are culturally more like Protestants. And the master culture and the Jewish culture are similar in that they both believe there is a group of people chosen by and most pleasing to God, and that in the modern era these people are wealthy merchants and bankers.
These similar beliefs allow Jews to cooperate with the master culture, although as much as they emulate it and as close as they get to it, they are not part of it. The master culture itself is very low profile. Perhaps the one significant difference it has from Jewish culture is its desire to remain as unseen as possible. Jews on the other hand maintain a distinct ethnic and cultural identity, and out of ethnic pride like to be visible.
So, the Episcopalians let everybody think the Jews run things, and they let the Jews think they run things. This serves the interests of both groups.
Much is made in the left wing press about the ethnoreligious background of some second rank officials of the (pro-war) Defense Department. Nobody ever mentions the ethnic or religious background of the (anti-war) State Department or CIA.
