Well if you are willing to become a pilot then simply pay the money. No disadvantage for you there.
As long as the airline sponsors it, they can take who they want IMO. If they are searching for a smurf with three eyes because they like the idea, then it's the way it is since they are investing their money.
These national restrictions are usually with airlines that have a close connection to government, since obviously the country will first serve it's own citizens before considering others. That aside, it's simply less struggle with bureaucracy.
