I understand that a blog post can't include a lot of nuance. But how does the role Jews played in creating/leading labor movements and related in the U.S. and (when possible) in Europe--thus becoming the internationalist Left menace rather than the Right one--fit your theory?
I have been reading Peter Weiler's biography of Ernest Bevin, a major figure in British trade unionism and socialism, and who became Foreign Secretary in the Attlee government that commenced in 1945, unseating the Tories.
Bevin was a well-known antisemite, but I had never seen a left critique go so far as to claim that Bevin's "socialism" was intended to control Jews (a.k.a "finance capital"). Weiler's argument is that labor and industrialists shared the same interests because a profitable corporation could raise wages and living conditions of workers without revolution; but finance capital, inevitably exploitative, drained industry of those profits that could also benefit workers. Enter the enforced class harmony of the British (or American) welfare states.
