Time to bring in the casinos.
I understand that's why the Burj was built 300 metres offshore - so it could operate as a casino, but technically, not be in the Holy Land where such things are forbidden.
However, on the day the (old) sheikh was to sign the papers making it so, one of his sons was killed in a motorcycle accident, and he saw that as a sign from You-Know-Who that he should not go ahead with the casino.
(I'm standing by to be told that I'm totally wrong by Sir Donald or one of the other company 'plants'.)
Dubai is / was a snowball system, an economy based on property investment with the hope, that when you invest you will find another guy to pay you even more in the future.
As someone has said before me = Ponzi Scheme, of grand proportions.
