Not since John Rawls’s A Theory of Justice in 1971 has a work of political theory been as rapturously received on the left as Thomas Piketty’s Capital in the 21st Century. The book having reached the summit of the Amazon sales chart in the United States, its 43-year-old French author, who visited London last week and whom the New Statesman was the first British publication to profile, has become that rarest of things: a celebrity economist.
In this supposedly superficial and anti-intellectual age, his 690-page treatise on inequality, rich in empirical research, has resonated because it speaks to one of the central anxieties of our time: that society is becoming ever more fragmented as the very rich pull away from the rest. As Mr Piketty elegantly demonstrates, as long as the rate of return on what he calls capital continues to exceed the growth rate of the economy (as it has done since the 1970s), inequality will widen to levels unknown since the Victorian era.
