"Lastly, some of Piketty's errors were transcription errors. In other words, GIGO (Garbage In Garbage Out). Therefore, using Python while there were GIGO issues isn't going to solve the data problem." More importantly the people claiming there are errors in hi work are making an even clearer error than Piketty in claiming that inequality hasn't risen. It has, and it is shown on dozens of measures. That they are trying to fight something as well established in main stream economics as evolution is in biology leads me to believe that in this case it is ideological windmill fighting more than honest critique.
