Trotsky repeatedly repeated the old antisemitic "canard"

"The Nazis abstract the usurious or banking capital from the modern economic
system because it is of the spirit of evil; and, as is well known, it is precisely
in this sphere that the Jewish bourgeoisie occupies an important position."

- Leon Trotsky. June 10, 1933

Nowhere are there such rich Jewish capitalists, bankers and usurers as in America. Over

there they shamelessly exploit and oppress the American workers – Anglo-American,

German and Jewish alike. On the American stock exchange, in the American banking

world, in American war industry, in the American press, Jews, in the capacity of

capitalists, bankers, lawyers and bourgeois journalists, play an immense role.
