I didn't say Marxism. I said Marxian... But I'm assuming you're actually what you're accusing me of, someone who scans wikipedia to form an argument he has already made and thus you don't know that 19th century Socialist movements, the basis for modern socialist beliefs, literally derive their definition of socialism from Karl Marx's writings...

And no, unions exploded because the industrial revolution and its emphasis on productivity and value. And the pioneers of labor unions were undoubtedly driven by the Ricardian labor theory of value, which is inarguably a capitalist theory. The leaders of both the Knights of Labor and the NLU, which were at the forefront of the labor movement, were driven by this.

You're fucking stupid and have literally no idea what you're talking about. But your argument about unions being an achievement of socialism is a pretty good example of socialism in that it takes the accomplishments of others and attempts to dole them out to those uninvolved.
