Bijou, which Dubai did you live in? It isn't where I live.
I am a single mother; I work, I don't have time to hang out with bored expat housewives asking me what my husband does. If such a breed exists
I live in Mirdiff, in a compound of 18 houses with about as many nationalities (including Emirati). The variation in rentals across Mirdiff is enormous. There are families there who are struggling, and those who are very comfortable. Just like most parts of the UK. I really have no idea where you get your 'housing separated by wealth' thing from. I suppose most of the houses in the Springs are similar size so assume similar price; is that what you are talking about?
I went to (a private) hospital when my DD had what turned out to be rotavirus. They were more than happy to attend to her and let me sort out the insurance forms afterwards.
Of course there are free beaches; that part of your post makes no sense. If you want luxury pools and bars and recliners, you have to go to a hotel beach, but if you are happy with just sand you have free options. And to go into a beach park (Jumeirah, Mamzar) which is nicely kept costs next to nothing.
You have to pay to go to the big parks. You don't have to pay to go to the little ones. We regularly go to the park for free. You can go camping/dunebashing/wadi bashing/without paying anything; you can go to places like the Discovery Centre and the Arabian Wildlife Centre for next to nothing (gasp. Sharjah. Shock horror). Or eg Children's City in Creek Park, or everything that is in Mushriff Park (less than 2 pounds for a car full of people)
Some high street stores do that with the charges; others don't. DEWA may be that expensive; I can't remember what I paid in the UK, but the UK doesn't have to desalinate water - it figures that water here would cost more (and after all petrol is a fraction of the price)
The driving is improving, believe it or not - I have been here for 10 years and it is a lot better now than when I arrived (and there are not daily fatalities. There are more than there should be, of course, but you are still exaggerating).
You didn't like it - it doesn't mean you need to present a false picture of it; it has plenty of genuine flaws (again, it is a young country. It is getting there). And there is no need to be sanctimonious vis a vis those who are doing their bit to help things develop in a positive direction.
