"Dubai is finished just go home or don't bother coming" is what some people are saying about Dubai. It's not true.
Why I think Dubai has a bright future? Dubai is a city state and a regional center which relies on global markets just like Hong Kong and Singapore.
Hong Kong, Singapore and now Dubai boom more than other countries during the good times and bust harder during recessions. Thats why the Hong Kong and Singaporean governments save so much money during the good times to get them through the bad.
I lived in Hong Kong during the Asian Financial Crisis, DotCom bouble, 911 and SARS and it bounced back each time.
Dubai (or the world) may not see such boom days again but it will get better.
