Didn't love this Graeber book. While I'm inclined to agree with the thrust of his arguments, I don't think his claims are quite accurate, and indeed empirical research questions their accuracy: www.cam.ac.uk/research/news/one-in-twenty-workers-are-in-useless-jobs-far-fewer-than-previously-thought

I think a more nuanced and less hyperbolic approach would make the argument feel more convincing and less baldly ideological.
