Is life in Dubai expensive?

Dubai is as expensive as any other well developed world class city in the world. You won't feel it is expensive as far as you are in good business and earning well.But the major part of monthly expenses include accommodation rent, school fees, medical expenses and utilities.

Yes.

..............................

Well, it's completely depends on how you want to live here..

Here you can see a blue collar worker earning AED 800 (USD 217) per month and a guy who is earning millions living happily. It all depends what you choose... 

Only if you're not a Saudi Prince

Well the UAE has a GDP per capita of over $70,000 US per citizen so prices and lifestyle would be quite high.

There would be poorer neighborhoods where the foreign workers live but I would not recommend that.
