Britain's choice of a Canadian, Mark Carney, to run the Bank of England could usher central bankers into the realm of globe-trotting elites that dominate the top jobs in business. Peter Spiro, a citizenship expert at Temple's Beasley School of Law, said the traditional sense of national loyalty is being tested as business goes global. "Those questions have mostly been taken over by globalization," he said, adding that Carney's selection is "a mirror of what's going on in the context of multinationals."
