Mensa is spot on with his assessment, one of the best I have seen. I would argue that Dubai and the airline will pi** you totally off a bit quicker than his 4 to 6 years, as the decline is like going down the back side of a drag curve (accelerating rapidly).
A tough decision to be honest, never under estimate the benefits of living among civilised people, where you have some rights, even though you don't notice or exercise them on a regular basis.
