>>The exact level of European inequality in the last fifty years is impossible to determine, as it depends on the sources one uses. However, whichever level one picks, the lines in red in the graph show that – unlike what Prof. Piketty claims – wealth concentration among the richest people has been pretty stable for 50 years in both Europe and the US.
>>There is no obvious upward trend. The conclusions of Capital in the 21st century do not appear to be backed by the book’s own sources.
Of course the upper class wants you to believe that wealth inequality has not been increasing. Of course they want you to believe that things are fine and dandy. They want you to believe these things because they don't want their wealth taken away, either via taxes or via revolutions. And Giles is simply their mouthpiece.
Like Krugman, I'm looking forward to Piketty's defense. But I doubt the errors are anywhere enough to overturn his conclusions.
