With oil trading at more than $100 a barrel, Abu Dhabi holds a jackpot-winning ticket in the lottery of life. The emirate sits on reserves of nearly 100 billion barrels, about 9 per cent of the world’s proven supply. At today’s pumped-up price, its subterranean treasure is worth at least $10 trillion. That’s $10,000,000,000,000.Abu Dhabi finds almost nothing unaffordable. Were Croesus reborn tomorrow, he would discover that the Al Nahyan royal family could match his outlay. In recent years, hospitals, universities, hotels, museums, racetracks, golf courses, marinas, airports and a five-star airline have sprung up ex nihilo. When its naughty neighbour Dubai, which has very little oil, ran out of money, Abu Dhabi sent over $20 billion to fill the hole.
