"You don't see that in London." It's a sunny weekday morning in the Dubai International Financial Centre area in the heart of the United Arab Emirates' biggest city, and a peacock strolls by a table where a portfolio manager for one of the world's biggest hedge funds finishes their drink and describes their new life in the Gulf. This individual had moved from London a year before to take advantage of the tax-free status and warm weather that Dubai offers. They're not first and won't be the last.
