John Cassidy — Parsing Piketty: Is Wealth Inequality Rising In The U.S.?

Pretty detailed analysis from which Cassidy concludes:

In any case, the broad pattern from nearly all of the studies is one of rising wealth inequality, which is the story that Piketty tells. Some of the details are still hazy, it should be conceded. But, as far as the United States goes, the concerns that Giles raises don’t knock down the Piketty thesis.
