Some answers for you....
1)
Basing people in outstation would mean comlying with the local labour laws in that country. Unions, strict FD/DT etc...
2)
Dont forget the famous money carroussel here...60% of the salary you earn you will re-invest in the country,thus creating a fake mini economy but oh so important for little countries. If you decide to base people outside, the money just flows away...No good for all the friends and relatives of the companies management getting rich on our backs
3)
Living abroad = less controll over your employees.
Just a few reasons I can think off why so far QR and EK did not work with basings.
They will avoid it as long as possible but eventually it will happen...at least thats what we like to think...
