1. Airlines in the US are falling out of the sky like flies,
2. >60 (before last year) would not like to reserve as a junior F/O at the bottom of the seniority of any airline.

The pilots need jobs and the airlines need pilots. The typical reply from all expats >60 is that they just wanna keep busy and love flying. I call shenanigans on that one 'cos they deal with a lot of sh*t in India and stick through it 'cos they NEED the job. I get this impression of superiority on both sides and it's self inflicting. It is a symbiotic relationship and one attacking the other only harms both sides.
