The core of the this PFT/SJS debate is not whether 500 pilots can fly a CRJ, any monkey can be trained to fly an airplane. The problem is hiring pilots with low time increases the supply of pilots, or "qualified" candidates! These people are suppressing the career progression of the pilot group as a whole, at least pay wise, and shooting themselves in the foot. Don't you ever wonder why these programs are sponsored by airlines! Managements want this to happen, because economically, it increases the supply of airline pilots, and therefore decreases the labor price (wage rate). That's why people are pissed off!!! Especially because ALPA is not doing anything about it, and that is part of their job as a union...controlling supply, to get the highest wages! Read any microeconomics text and it will tell you this.
BTW, as I said previously, anyone can learn how to fly a CRJ, physical flying isn't hard! It's the management of airline flying that is tasking. Effective management if based on mainly on judgement, not skill. One can learn judgement through training but mostly through practical experience, and PFT's don't have practical experience. One might content that FO's will gain said experience in the right seat! This is complete BS! Though we all learn things every day, Regular Line Captain's are not there to teach you how to fly a CRJ. If this is what is going on, you are a liability, and threat to aviation safety.
IMHO ALPA should be installing hiring minimums in collective bargaining agreements. If there were minimums of say, 2000TT/800ME, it would decrease the supply of qualifiied pilots, and raise the median wage rate. It would aslo make PFT programs cost prohibitive, candidates would be forced to earn it the "old fashioned way," and therefore gain the proper experience to effectively manage as a airline pilot.
