You're halfway there. Plenty of people will shell out 100 g's if the downstream benefit is good enough. It isn't. The pay and (almost no) benefits don't justify the cost of training. Job security is VERY questionable to boot. If you really want to fly, at all costs, okay; otherwise it doesn't make sense. Put the money toward a professional degree, make MUCH more money, then get a license and fly on your (much more)time off.
Expats are a relatively small percentage of US pilots (about 800,000 total - I dunno how many ATP's). Most are over sixty or (like me) fed up. Glad to have a place over here, though.
