Malcolm X: You can't have capitalism without racism.

Without bigotry in general. The capitalist class always needs an "in-group" and an "out-group" to divide and conquer.

Sure you can, just look at Europe where there were essentially no black people! They don't have ... wait, no, they just found ways to be racist against other whites.

Except europe had that for centuries, oppressed their own people. Reducing class struggle to race dooms the working class, and misses the point, and history proving that wrong.
