I laugh every time somebody makes this statement, you have no idea as to how many people have and continue to quit jobs at mainline carriers in the US to go abroad, I am an example of it since I didn't accept a job with a legacy to come here, we have people here that have resigned their seniority to airlines in the US to continue their employment abroad, everyone has different reasons to do what they do, there is no right or wrong way and generalizing is unrealistic and pointless. I do agree that somebody in their late 30's has a long career ahead and it might be fruitful on the long run, but saying that the US expat community exists because they can't get a job in the US is a ridiculous statement, jobs there are a few in the US, jobs that pay 200+K a year with 14 days off a month, those are the ones that we can't get.
