The problem with ryan is not p2f, but the brookfield fraud. It is not paying to fly, but flying for less than standard (no vacations, etc...). They can still make a more or less proper selection of candidates, if they want, as many among those candidates with the money have talent and can be good pilots.
The ryr problem is a worker rights problem.
What is really wrong is when money bypasses selection so that better, more talented people cannot get a first job, while rich guys, good or bad, manage a job and the jet time that opens the market for them (well, right now it only opens the rent-a-job market, but quite a few managed to get real jobs thanks to buying line training in some misterious airline).
This goes against safety and against quality service, and passengers do not deserve that.
It is not illegal to fly transport airlines with a single pilot crew if the airplane is certified for that purpose, or is it? I wonder if airbus or boeing have studied the matter of having their new or even old models certified for just one man in the deck.
