"the chairman of Britain’s top financial watchdog has described much of what happens on Wall Street and in other financial centers as “socially useless activity”. In a recent article titled “What Do Banks Do?,” which appeared in a collection of essays devoted to the future of finance, Turner pointed out that although certain financial activities were genuinely valuable, others generated revenues and profits without delivering anything of real worth—payments that economists refer to as rents. “It is possible for financial activity to extract rents from the real economy rather than to deliver economic value”. Turner’s viewpoint caused consternation in the City of London, the world’s largest financial market. A clear implication of his argument is that many people in the City and on Wall Street are the financial equivalent of slumlords or toll collectors in pin-striped suits." - Simon
