I don't think it has anything to do with pleasing first world countries, but rather it's a matter of controller experience. If you're the boss, it makes sense to hire controllers who have been exposed to high traffic levels and modern equipment/procedures. (Even if we are sorely lacking in both these areas...but that's another topic.)
It's all supply and demand. Apparently Abu Dhabi can now pick and choose, which is good. As mentioned earlier, the system is not set up to train, but rather to convert. If an arline needs B777 pilots, you hire those with that rating. It's just quicker and cheaper than training a DH8 guy. !!!! analogy but you get the drift.
I feel for the folks out in left field, but that's just the way it is. Hope this helps.
