I met a local Rugby team in Barista Bar last year and they were all living it up big-time in Dubai. Discussion turned to people's pay and whilst everyone was better off than "back home", it became apparent that all of them were earning one third of my salary... but they were still having a good time with absolutely no intention of returning to their country-of-origin.
Some people are here for the money... and yes, some people are here for the lifestyle.
