As someone else has mentioned too, think of the money you'll be able to save. Your kids will get the experience of living abroad and understanding other cultures and if anything it should do well for their education. Think of the stories they'll be able to tell people.
Living as an expat in Dubai your kids will experience almost zero Arab culture as most ex pats live in exclusive communities full of other expats and attend the local American school with other expat kids! You have to dig pretty deep to find any substantial colour ute and tradition in Dubai!
I would happily take my wife and kid abroad but Dubai mega money or not just doesn't appeal!
