Sher-e-Hindustan: You're comparing apples and oranges. I had an uncle who worked in the Middle East for a few years. He was transferred there for a limited period of time by his employer. He was advised to leave his wife and children at home because he was told they wouldn't likely enjoy the Middle Eastern lifestyle. Sure, he worked there for the money but he wouldn't have ever described himself as an immigrant. He had no expectation that the society would adapt to accommodate him and no intention of staying. My suspicion is that the vast majority of westerners who move to work in Middle Eastern countries do so temporarily with little or no intention of remaining in the long run. To compare them with immigrants who move to the West, even if for economic reasons, is just silly.
