In his latest article he explicitly and approvingly cites Marx twice (with a few more implicit mentions) and comes up with two elegant destructions of common billionaire apologia arguments: " They don't do it for the money - then it should be no problem if we tax most of it away, right?" and "They worked hard for it - well, thieves can also work hard".

Obviously he has a number of very shitty takes but it's over the top to dismiss him completely.
