You said it yourself, it's not about the job, competitive or not.
It's about the life style. In third world countries there is not much of a life.
Had a friend once in Goose bay who used to say:"There is only fishing and fu..ing. In winter-there is no fishing.
Pretty much the same here. No social life, no clubs, bars, restaurants. No proper food, no educated people to talk to, no hobbies...
We're here for the cash, and happy when the airliner outbound goes "Gear up!"
Nothing else.
