Tallg is right. I expressed this same fact on another thread and people argued about it.

If the relocation packages are not lucritive enough to compensate for the hardship of leaving the comforts of home, people (most Europeans and Americans) will not relocate.

The Middle East is definitely a place where the packages are much more lucritive because of the different lifestyle and extreme hot weather.

Of course, there are some people that just want to relocate for the experience of it all.

Just to "hang out" in a Middle Eastern country to experience the way of life and such is not why the majority of westerners come here.
