To make it simple as a single FO yes you can save, not a problem at all, married however you will just survive. Slalak taking kids to school, school activities, sports, cable TV, Internet, Wifes telephone, entertainment movies ext ext . As an FO your salary is about half that of most other western expats, and is about the same as an office or small shop manager.
Also depends on where your from if your a westerner, there will basically be no one else in that lower wage bracket. If your from Egypt, Lebanon, Malaysia and the like you'll be on about par with your peirs working in semi skilled/semi professional management positions.
They are the facts, like it or lump it. And yes out side of Emirates wages very much depend on nationality, get use to that as well..
