>>20158I only read Capital in the 21st Century by him, and I don't think I even finished it because of the amount of repetition and redundancy.
Nonetheless, I agree he's an interesting and even useful writer. At the end of the day he's describing the gradual accumulation of wealth and growth of inequality through mainstream economics language, which might not be new to marxists but is an additional tool at the very least.
When talking to people who are not socialists about the world I often find myself referencing him, which is harder to do with marxian economists.
