One of the best things about Piketty’s masterwork is his systematic demolition of his own discipline. Academic economics, especially in the United States, has for decades been gripped by a kind of professional pretentiousness that is close to pathological. From time to time its great minds have grown so impressed by their own didactic awesomeness that they celebrate economics as “the imperial science”— “imperial” not merely because economics is the logic of globalization but because its math-driven might is supposedly capable of defeating and colonizing every other branch of the social sciences. Economists, the myth goes, make better historians, better sociologists, better anthropologists than people who are actually trained in those disciplines. One believable but possibly apocryphal tale I heard as a graduate student in the ’90s was that economists at a prestigious Midwestern university had actually taken to wearing white lab coats—because they supposedly were the real scientific deal, unlike their colleagues in all those soft disciplines.
Piketty blasts it all to hell. His fellow economists may have mastered the art of spinning abstract mathematical fantasies, he acknowledges, but they have forgotten that measuring the real world comes first. In the book’s Introduction this man who is now the most famous economist in the world accuses his professional colleagues of a “childish passion for mathematics and for purely theoretical and often highly ideological speculation”; he laughs at “their absurd claim to greater scientific legitimacy, despite the fact that they know almost nothing about anything.” In a shocking reversal, he calls on the imperial legions of economic pseudo-science to lay down their arms, to “avail ourselves of the methods of historians, sociologists, and political scientists”; the six-hundred-page book that follows, Piketty declares, is to be “as much a work of history as of economics.”
Admittedly, I stalled out about 25% of the way into Capital in the 21st Century, but it is an extraordinary "informational text."
