Ruchir’s prose is youthful, intellectually flirtatious and lucid, most unlike the dense language used in economic tomes. I love the way he weaves in history, cheeky humour and the touch-and-feel realism of a travelogue—most evocatively, a jungle safari. “Big cats are programmed to survive by conserving energy, not to waste it in constant motion.... And they don’t panic over cyclical turns in the weather.” His wit is crackling when he divides his book between BC—Before Crisis (2008)—and AC, After Crisis. I guffawed audibly when he rechristened BRIC (Goldman Sachs’s much celebrated, but derided post 2008, acronym, ie the Brazil/Russia/India/China super performers’ club) as “bloody ridiculous investment concept”. He packs in big data unobtrusively, for example, “After surging for more than three decades, flows of capital reached a historic peak of $9 trillion and a 16 per cent share of the global economy in 2007, then declined to $1.2 trillion or 2 per cent of the global economy—the same share they represented in 1980”. In a silky punch to the solar plexus, he tells you how precipitously, perhaps irretrievably, the global economy has somersaulted into an autarchic repast.
