GR - Dead wrong. I had a job with a European legacy and moved here out of choice. My old airline makes a healthy profit and is not in danger of shutting down.
I moved out here for myriad different reasons, I don't regret doing it having lived out here for a few years now and I would make the move again without hesitation.
There are plenty of people here in the UAE who are the same, while I think you have a point about Qatar, many people also want to broaden their horizons - I couldn't stand the thought of spending the entirety of my working life flying A320's around Europe.
You can't broaden your horizons much more than working out this way...
