Dubai, United Arab Emirates

Capital City

With a population of 3.9 million, 92% of whom are expatriates, Dubai is a glitzy mirage that can be a harsh reality for those who don't fit the mold. The tax-free haven has become a top global tourist draw, but its rapid construction and real estate speculation have also made it a hub for money laundering, with lax regulations allowing dubious characters to park their wealth. Persistent bureaucracy and a desert climate that can be punishing in the summer are other persistent headaches. Dubai is best suited for those drawn to its tax advantages, luxury lifestyle, and opportunities in finance, trade, and tourism - but may leave others feeling like outsiders in a city built for the wealthy elite.
