Gilad Atzmon, noted author and blogger, wrestles with popularized notion of JEWISH GENIUS. He confirms and traces "tribal eugenics" that led to a distinct Cognitive Elite among Jews quite a bit superior to other ethnicities.
Essentially, ghetto life compelled Jews to marry gifted boys with daughters' of rich merchants thereby combining "cleverness" with "money."
This fifteen hundred year experiment in eugenics bore fruit. Once liberated from Ghetto life following the French Revolution, Jewish Elites maneuvered to control Europe within forty short years.
Atzmon credits, as well, the Tribe's Focused Assistance to its Elites-in-the-making. Poverty was generally no obstacle to Ghetto Jews with talent obtaining a quality education.
Noteworthy, breeding an ELITE corps robbed the mass of Jewish non-elites of smarts. Moshe, Chaim, and Josef, he observed, can be painfully average - fit for labor only.
We see evidence of "Cognitive Ability + Sophisticated Clan Help" operative today. Media Mogul of Estonia was a moneyless talent made rich by Rothschild interests to control Jewish viewpoint in Estonia and beyond.
Another classic example would be Rupert Murdoch who started with a single, medium-sized Australian Newspaper then catapulted to Global Media Baron - again he enjoyed Rothschild backing.
This concept of Cognitive Elitism explains, in no small measure, why Jews occupy power posts and set policies for lesser-gifted Goyim.
This concept of Cognitive Elitism explains why Israel routinely targets for assassination Palestinian Leadership Talent! Killer drones quite literally keep Palestinians dumber and more subservient.
