May be strange coming from me but:
UAE nationals are outnumbered something like 15 to 1. It is to be expected if at times they may appear to be overzealous towards their own. Given the same ratio in any country one would expect the same to happen.
I spent many many years in the UAE and it was an absolute pleasure and honor to be considered and treated as a friend by the locals. It wasn't easy adjusting but once achieved it really is a fantastic country.
The real issue I suspect is that terms and conditions are not what they used to be in real terms. But this is part of the bigger aviation picture which many don't want to accept, the industry is changing and changing for the worst. Get out if you can, especially if you are young but don't turn your gripes into a racist or nationalistic thing because that is not the problem.
