Thomas Piketty's 2014 book, Capital in the 21st Century, is the rarest of tomes — a 700-page best-seller on economic theory. The French economist was transformed into an international celebrity, arguing with uncanny timing that economic inequality has worsened since the 1970s, and contributed to social and political instability. The political upheaval of the last year has only made him seem more prescient.
But there is much debate over Pikkety's central premise explaining why inequality has grown worse. Among those challenging Piketty is Devesh Raval, an economist with the Federal Trade Commission, who tells Axios that the Frenchman wrongly blamed automation. Instead, says Raval, the culprit is globalization.
Between the lines: If Raval is right, and not Piketty, then we have already seen the worst, and inequality should stop becoming exacerbated. "If globalization and trade are the culprit, most of those effects should have already happened," Raval says.
