¡Ay Caramba!
In the USA, the working class have always been cosmopolitan -- they have come from all over the world, beginning with enslaved Africans (who were not wage workers but were closer to the conditions of the proletariat than much of the rest of the New World inhabitants, in the sense that they were more decidedly separated from the means of production than white artisans & petty producers). Think of industrial workers early in the twentieth century; they were mainly immigrants speaking a multitude of languages, with flourishing foreign-language presses & social institutions. Examine the history of pan-Africanist consciousness among black workers & petty producers in diaspora. Consider the need of today's labor organizers who had better speak at least Spanish. Analyze where a lot of "knowledge workers" come from -- India, China, Eastern Europe, etc. (science in American universities would be dead without international grad students & professors).
I'm simply making an effort to bring ideology in line with social reality.
