I'm all for an increased wealth tax, and raising awareness is good, but saying that it would be the simple, complete solution as he implies is misleading. Gary also refuses to engage with the research, talk about specifics, show graphs and explain how wealth inequality is a complex issue in his videos. He simplifies things to the extreme and defines society in terms of he and his audience as the pure, non-elite people on one side and all economists and the corrupt elite on the other. This, along with the way he presents himself is why I believe that unfortunately his style is somewhat similar to that of populists on the right, even if their aims are very very different. I'll provide some sources for high quality critique on Gary's work as a reply to the other comment.
