My take too. I also fail to understand why anyone here takes their nonsense seriously.
If you have not read Economic Facts and Fallacies, I highly recommend it.If we can kick the Piketty and Saez legs out from under the progressive narrative, it will collapse. The more I see, the more I realize that almost all the "facts" the progressives use are based on these clowns and their BS studies. They crap it out, then Krugman and Reich put their spin on it, then the NYT picks it up, then it is "common knowledge".
It drives me crazy.
