The first and most obvious reason why this doesn't happen is because the lifestyle of the erudite is characterized by the quiet introspection and intellection afforded by solitude and rest, not throngs and exertion. Chronic pondering conduces to inaction. The next obvious reason is because intellectuals are famous for hating each other. They can't get their collective act together long enough to organize and execute campaigns for public office. Finally, Jews more than other peoples find agreement generally distasteful, dooming the prospect from the outset. Yet all of the above are merely stereotypes; they do not monopolize truth and therefore leave room for hopeful aspirations to upset assumptions.
