This thread seems to have gone way off track and become a political rant about comparative social and political systems and those can be debated for ever in total disregard to the history and future needs of the countries concerned. The Gulf has given crews from all over the world tremendous opportunities and opportunities they could not have expected in their home countries, especially those dominated by legacy carriers. If having got there they find they don't like it-and the lifestyle while great for some is not for others,- no problem,- just leave.
As far as aviation is concerned the fact is that Canada, with its geographical position and its old fashioned restrictive bilateral agreements which limit airline frequencies and capacity is an international backwater of little interest to most carriers. A look at an atlas will reveal that the Gulf on the other hand is probably the best located place in the world to base an airline aiming to provide one-stop flights from almost any part of the globe to any other. (Ok, Ok, not from North to South America or American continent- transpacific). The new carriers have taken the opportunities well and provide levels of service up there with the Far Eastern airlines, and way above most of the Europeans and even further ahead of the legacy American operators. Air Canada doesn't even begin to compete in this respect.Let the customers choose.
