Train-
Well, you have your four year degree, well networked and the hammer may or may not drop, I think you're in a much better position than the recent high school grads with $80K of flight training debt and no degree.
The airline business is like a marriage. It's got ups and downs. Hopefully the 'ups' are deliciously fabulous, and the 'downs' are few and far between.
Everyone else- You effers'll be fine, stop worrying so much!
Those that took the advice we've been doling out for the last decade will be alright. Those that didn't, well, bon chance mi amigo!
It is what it is and enjoy the ride.
