Politics and business ethos never on a level playing field. Purely politically, I favour jobs for the locals. Purely on business lines, I favour jobs for the more suited and talented. The two go head-to= head when you have too many foreigners and too many locals. It has been like that for decades in the Middle East. I know many who enjoyed the latter location for decades but most were aware that it would only last until the locals, simply outnumbered the foreign guests.
All of us pilots tend to develop loyalties very quickly and enjoy getting into the team spirit. When flying for a foreign airline in a foreign country on a RV/work-permit the team spirit and desire to "belong" is very misguided and doomed to transition rather than permanency.
Very sad and even moreso when it is time to go but nothing to go back to.
