There are uses and abuses of class separatism. It draws clear lines of demarcation, helps sort the ideal from the material, and finds issues that cut across a lot of differences. But it gets abused, and the abuse is rooted in its mistake about relations of production. My contention, having done this assessment of class separatism, is that the abuses are actually a feature, not a bug, in class separatism as a concept of relations of production. Individual and structural elements are each necessary and sufficient elements of relations of production. The trouble starts when organizers and intellectuals place more weight on one rather than the other.
