Carl,
Wilbur and Orville had to flip a coin to determine who was going to fly the first airplane. Our profession had literally not even gotten off the ground before there were two pilots for every job.
That's why we started ALPA. To prevent senior pilots being replaced by junior pilots willing to do the job for less and take imprudent risks to secure employment.
The very foundation of our need to unionize is born of the fact that someone else wants your job and management is happy to give it to them.
Blaming the regional guy (who has no say int he matter) is politically expedient, but fails to fix anything.
It is a job for a union.
... and yes, I would take your job as 747 Captain. No offense, but it looks like a good gig from here.
