From those that start pilot training, there are relatively few that will achieve a good airline job. I have seen friends of mine who have made it all the way through to fATPL and never worked as a pilot. I have seen friends who have made it as far as jet FO and been chopped because they haven't quite 'got it' in the small amount of time an airline will give you to improve.
In your position, if you haven't started, I wouldn't touch aviation as a job. You say you have a house, a family and a good job. I would go and fly for fun.
Your question shouldn't be can I get a job north or south. It should be can I get a job which actually pays? If so, which country is the job in? The rest is all luck, ability is assumed if you manage to get that far.
