i have stayed in Middle-east for a while in late nineties and i have to say that things have changed from those days.
yes, it is easier from somebody from south asia or far east or africa to get comfortable here because life generally is easier, money better, and way way safer for a family.
however, even then most of them will rue about the weather, the horrid night flying, the sheikhdom, the second class status etc. etc.
you will never be able to call it home. just come for a few years, make some money for retirement and go back.
a long term view is desirable but make no mistake--it may frustrate you sooner than you think.
