From The New Yorker:
In the fall of 2003, Anil Kumar, a senior executive with the consulting firm McKinsey, and Raj Rajaratnam, the head of a multibillion-dollar hedge fund called Galleon, attended a charity event in Manhattan. They had known each other since the early eighties, when, as recent immigrants, they were classmates at the Wharton School of Business, in Philadelphia. Their friendship, intermittent over the years, was based on self-interest rather than on intimacy.
Kumar, born in Chennai, formerly Madras, India, was fastidious and morose, travelling at least thirty thousand miles a month for work, and seldom socializing. Rajaratnam, a Tamil from Colombo, Sri Lanka, was fleshy and dark-skinned, with a charming gap-toothed smile and a sports fan’s appetite for competition and conquest. Kumar was not among the group whom Rajaratnam took on his private plane to the Super Bowl every year for a weekend of partying. “I’m a consultant at heart,” Kumar liked to say. “I’m a rogue,” Rajaratnam once said. Kumar had the more precise diction and was better educated, but Rajaratnam was one of the world’s new billionaires and therefore a luminary among businessmen from the subcontinent. In an earlier generation of immigrant financiers, Kumar would have been the German Jew, Rajaratnam the Russian. Kumar might have felt some disdain for Rajaratnam, but Rajaratnam’s fortune made him irresistible.
