Well, maybe. Age permitting, the bottom of a cycle is the best time to get aboard and the top is the best time to cash in your chips and walk away. Your story indicates that you probably did the right thing by going into construction when you did, but the wheel continues to spin. No matter what becomes of the airline pilot profession, there will be those who say "I knew that would happen." But they really didn't. And there will be those who kick themselves for having made the "wrong" decision. But they really shouldn't. Research, choose, work, and then accept. Repeat as necessary.
