This was a fascinating read. Essentially Varoufakis argues that capitalism is actually over, and that we are now in an era where rent derived from "digital fiefs" is dominant (e.g.: Amazon doesn't produce goods or acquire capital in the tratitional sense, but because no seller can survive without selling on Amazon, it operates like a fief extracting rent from the vassals (sellers) who have no option but to use their site). It's pretty heavy economic theory, but he frames it as a conversation with his late father, and does a good job at simplifying and explaining what he talks about.

Very interesting, and very convincing.
