P2F is wrong, but the system is wrong, when 500 hours 737 time line training is cheaper then paying to fly a light twin!
Simple economics dear boy. Why pay an F/O 35k pa plus all of the associated costs associated with employing staff when the wannabe will pay you 50K for a rating and 500 hours. That is a net saving of 85k. Means you are only paying the Captain and you can even afford to pay an extra 10-20k a year given that they will likely be a minimum of a TRI to fly with the newbie. Although in reality you will probably find some idiot who will do the TRI bit for little if any additional pay.
P2F will only go away if there is legislative change or if it can be proved that there is an adverse safety impact form P2F. I can't see either happening nor can I see wannabes who can afford it sticking to their principles.
Bull*hit walks and money talks and all of that. Same goes for anything in life.
