Democracy in the Twenty-First Century

NEW YORK – The reception in the United States, and in other advanced economies, of Thomas Piketty’s recent book Capital in the Twenty-First Century attests to growing concern about rising inequality. His book lends further weight to the already overwhelming body of evidence concerning the soaring share of income and wealth at the very top.

Piketty’s book, moreover, provides a different perspective on the 30 or so years that followed the Great Depression and World War II, viewing this period as a historical anomaly, perhaps caused by the unusual social cohesion that cataclysmic events can stimulate. In that era of rapid economic growth, prosperity was widely shared, with all groups advancing, but with those at the bottom seeing larger percentage gains.

Piketty also sheds new light on the “reforms” sold by Ronald Reagan and Margaret Thatcher in the 1980s as growth enhancers from which all would benefit. Their reforms were followed by slower growth and heightened global instability, and what growth did occur benefited mostly those at the top.

But Piketty’s work raises fundamental issues concerning both economic theory and the future of capitalism. He documents large increases in the wealth/output ratio. In standard theory, such increases would be associated with a fall in the return to capital and an increase in wages. But today the return to capital does not seem to have diminished, though wages have. (In the US, for example, average wages have stagnated over the past four decades.)
