The straight answer to your question is I don't know.
However I have friends who worked in Dubai for 2 years, a married couple, he was in a very high power government job. He was pro-vice chancellor of a University and had been head hunted for the job. Very good salary, very attractive working conditions. They hated it. They couldn't drive anywhere they had to have a driver, for two reasons, she wasn't allowed to drive, so she had to have a driver. The driving conditions were very bad so a local driver was needed to 'protect' them. Foreigners having car accidents are at fault. The weather during the hot season was unbearable, and they are South Australians and we get hot weather. Entertainment and social life was basically limited to other foreign nationals. As he was a high ranking Government employee he rapidly found that he couldn't do his job because no junior government officials were allowed to make decisions, and senior government officials were not allowed and freedom in decision making, they had to refer everything to members of the ruling family.
As his task was to 'Westernise' the particular university, or at least bring it into a Western success model, his job became untenable because it contradicted what the ruling family accepted as their desire.
Thee reason he took the job was that he was assured that Dubai was different to the other middle eastern oil rich countries and that they had a true desire to move forward into a 'western' economic and social model.
He decided that this was not true when the practicalities were involved.
It was sort of Catch 22 with spin.
I also have friends who have just (last week) returned form a holiday in Africa, the stopped in Dubai for 4 days on their return. They are originally from India, they said that they had no racial problems and people were very friendly but that the heat was unbearable, and that the locals also said no one goes out during the hot season unless you really have to.
