There were plenty of Jewish working class in the early 1900s that advocated for Communism so that they could enjoy the communal fruits of their labors instead of just being handed pathetic wages. In fact, there are still plenty of Jewish working class that feel pretty much the same way about the modern representations of Communism (national health care, etc.).
