Thomas Piketty is the new wonder-boy of redistributionists.

The Financial Times reports, however, that his numbers are off, skewing his findings, Piketty findings undercut by errors (h/t Sean Davis):

Thomas Piketty’s book, ‘Capital in the Twenty-First Century’, has been the publishing sensation of the year. Its thesis of rising inequality tapped into the zeitgeist and electrified the post-financial crisis public policy debate.

But, according to a Financial Times investigation, the rock-star French economist appears to have got his sums wrong.

The data underpinning Professor Piketty’s 577-page tome, which has dominated best-seller lists in recent weeks, contain a series of errors that skew his findings. The FT found mistakes and unexplained entries in his spreadsheets, similar to those which last year undermined the work on public debt and growth of Carmen Reinhart and Kenneth Rogoff.

The central theme of Prof Piketty’s work is that wealth inequalities are heading back up to levels last seen before the first world war. The investigation undercuts this claim, indicating there is little evidence in Prof Piketty’s original sources to bear out the thesis that an increasing share of total wealth is held by the richest few.

Prof Piketty, 43, provides detailed sourcing for his estimates of wealth inequality in Europe and the US over the past 200 years. In his spreadsheets, however, there are transcription errors from the original sources and incorrect formulas. It also appears that some of the data are cherry-picked or constructed without an original source.

I think Rick Perry had a reaction once similar to what Piketty worshippers should be having:
