What do you expect?
DXB no oil left, inflation at a real figure of 22% and growing, who the heck would go to DXB. That's not counting the road traffic et al. Tourism ain't going to get them back.
DXB & the rest of the UAE will survive, but at a realistic rate, it's not a gold mine. When you're there, you're only an expat to be used and sent home when you're use has been exhausted, are you surprised?
Been to/in the original sandpit/new sandpit, learnt the leasons, and still happy. As long as you understand the status quo, you're fine.
