Simply put, when airline management knows an individual will pay for a job, then they charge big and turn it into a profit center. Management then correctly decides to pay bottom dollar said individual poverty wages a year to fly their customers around. Then they figure they can skimp on benefits, etc since said individual is willing to allow management these benefits. It rolls uphill, next company sees pilots are willing to do anything to get said job, Voila, profession runs downhill. Repeat. Many in the profession want to break the cycle, not perpetuate the cycle. I don't blame management. We are a capitalistic economy, so it is up to each pilot to pull to better our profession. Jonathan Ornstein now at Mesa stated when I was at the old COEX he did not want us to hang around, cheaper to keep churning the pilot group. (Besides, it is a profit center to "train" pilots to work at the company) Lower wages, more profit for him/company/stockholder. Bad for pilots as a profession. We wanted to put it into the contract that PFT would not be allowed, it started 2.5 years after I showed up because the industry was stagnant. Did not fly. IMO all unions should fight the concept to help new guys out. i.e. put it in the contract. Right now, things in market opposite, so good time to get it in for when the market collapses again.
Many see the folks you describe as counterproductive. I will let them ride though. Also, it isn't appropriate to call them scabs unless they are, that is a word that should truly be left for the scab and not diluted. Oh, and pilots are a pilots worst enemy. One of the contradictions of life that is true.
