@spoltier This work derives in part from my work with Nolan McCarty, you might want to read his books on inequality & political polarisation -- one is a leading academic text (with two coauthors) the other is an effort at popular writing. A graph is here https://joanna-bryson.blogspot.com/2016/06/robots-are-owned-owners-are-taxed.html The other part is my work on antitrust with Helena Malikova. For that I'd recommend reading Tim Wu's book "the curse of bigness," particularly on the history of antitrust.
