Obviously I cannot speak for anyone else, but if you are that close-minded about the Middle East, I am not sure anyone could give you a decent answer.
Personally, I applied for several reasons... I wanted to expand my knowledge and experience to include working under ICAO rules... I wanted to learn about cultures other than my own... I wanted to travel and see the world... and I wanted to try to save a little money. Here, I can, and have done all the above.
The packages offered here differ greatly in thier structure and application, but the bottom lines are usually pretty close. But you get paid to do a job. If you think the traffic or conditions are something you may not like, then dont apply. Certainly not just for the money.
I was raised in a very green area with moderate temps... and it is a beautiful place. But the Middle East is just as beautiful... you just have to open your eyes.
Of course, YMMV....
