I read this book and, to be honest, did not enjoy it very much. It consists largely of profiles of people involved in this sort of philanthrocapitalism. The main theme seems to be that the ultra-wealthy have coopted the work of social institutions in such a way as to undermine efforts for truly revolutionary change, that is change that might threaten them. The premise is interesting but the content is pretty boring. I got tired of reading about people whom the author believes to be mislead or malicious or otherwise on the wrong path. For those interested he gave a talk at Google in Cambridge that was pretty good.

It's a worthy topic, and a solid complement to Piketty's work.
Investigating and articulating the "apparatus of justification" is helpful.
