As bronx said, Dubai followed a similar strategy that was followed by Ireland and also by England back in the 80's and the whole UK during Tatcher's era, i.e. increase the value of Real Estate, noting that it is mainly owned by locals, and this by encouraging speculation, establish an efficient platform for financial transactions, have cheap foreign labor do the job for the you, and just cash money from rents and mostly-silent partnerships.
2 opposite visions regarding its future: some say that the situation is not as dramatic as it seems, that the bottom is reached and that Abu Dhabi will bail out when needed to prevent a total collapse, awaiting global economy to recover, i.e. 2-5 years. Others would tell you that Dubai will never recover as its Real Estate sector will never be able to recover from the crash. Lots of uncertainty though.
i never was able to understand why people tend to compare Beirut and Dubai.
A 4,000 years old city and a 20 years old one, each has its advantages. Beirut has a weather, has culture, initiative, 10 Million people spread all over the world as well

. Lebanon geographic position is an advantage but it is also huge a huge disadvantage, being the weak link in the heart of one of the oldest conflicts still prevailing. Dubai has political stability, which of course, allowed its leaders to have time to plan and create a vision. Of course it is easier to establish a company and make business from Dubai, of course its last economic boom created jobs and opened doors, but as you have all seen, how many dollars stayed in Dubai when the crisis started? everybody pulled out. i.e Dubai was an opportunity for many, but only a punctual opportunity. While Lebanon has resisted so many tougher hurricanes. Speculation v/s investment, there is a big difference and it tells a lot. It depends from what you want, the kind of life you want and of course, it depends on the opportunities you get. i am sure that esam would have never thought twice to live in Lebanon should Lebanon be able to offer him the same job than the one he has abroad.
