Take a look at those areas I referred to in my previous comment and you'll see that your image of Dubai is but one part of the wider picture. Ask yourself if the West End and the City are all of London or if Beverly Hills is all of LA?

Plenty of people live in Karama and Bur Dubai (i.e. not in Sharjah), for example, who are not especially rich - those parts of Dubai are in fact the oldest and most populous parts of Dubai! Visit those places - don't just go to the usual tourist traps of the Palm, the Marina, and Downtown!
