I disagree with a good bit of this, though it's a million times better than some super liberal stuff.
I guess here is as good a place as anywhere, but I always find it super interesting how alienation is treated. Alienation was something which Marx wrote about early in his life, and people say 'he didn't develop the idea', but I always read it as something which developed into other core ideas: commodity fetishization and exploitation. Alienation is a generic term for the specific relations to production, with commodity fetishization being from the perspective of consumption and exploitation from the perspective of production.
