What does Dubai do?

""An entire industry has emerged in Dubai serving people who are transiting on the way in or way out of Kabul, Kandahar or Baghdad. It seems to exist to process large groups of loud, drunk South African PSDs coming out or sad-faced contractors going in. The young Filipino women who did our spa treatments -- knowing, without us having mentioned it, that we'd been in Kabul -- said that 80% of her clients had been in or were going to Kabul. It made us wonder to what degree the economy of Dubai depends on the wars in Afghanistan and Iraq, rather than money laundering, Russian prostitutes and overvalued real estate."" (thanks anonymous)
