As Ha Joon Chang points out in his book Economics: The User's Guide, economics is about political arguments yet pretends as if it's a science. Hence most economists don't like the politics of Pinkety's economics. Which is what the op was alluding to though he did not mention explicitly... because they depend on money from people who don't like forwarding that political agenda. Secondly, it seems that the math that he used to make some of those arguments is not up to par so that makes it easy to dismiss his political arguments, and that's the issue when you go up against the status quo you better have inscrutable math because they are going to find any reason to dismiss you.
