I have heard that Dubai is using the current economic downturn to reinvent itself.
Basically, tourism will target middle/upper class people mostly from India and the West. And they will try to deter the lower class Western tourist from coming. They will also place an emphasis on trying to attract wester Muslims.
They will reestablish Islamic values to protect their culture, eg clamp down on skimpy dresses and drunken behaviour by tourist. And forbid any behaviour that is socially unacceptable in the Gulf region.
They will use the recession to get rid of under qualified western expats that have no desire to integrate or have shown no respect for the Emirati culture and whose behaviour offends most Emiratis.
When the economy recovers employment will be offered only to candidates who have suitable qualifications and experience, no-more people who can't get a job in London, coming to Dubai in management roles. Also preference will be given to qualified western Muslims are more likely to integrate, have more in-common with emirati's and whose values and behaviour is closer to the Emirati culture.
