The problem for Guerrero and his cohort is that at their "age and experience" end of the spectrum, everything is about the 'oppotunity' of the future. For the greybeards amoungst us, we look back at the 'consequences' of our earlier oppotunites.
It is difficult to see the problem from each others point of view, but what is true is that the barrier to entry for becoming an airline pilot has never been higher.But, even now, there are oppotunities for the dedicated and flexible. It is easy to blame youth for taking the 'easy' route to the RH seat of a jet. If credit had been easy or daddy had made a wad on his house, I'd have probably tried to avoid the years in GA, certainly my pension might look healthier than it does now, who knows. But then I would have missed out on some remarkable adventures.
But taking the easy money oppotunity has had the unfortunate consequence of bu**ering up the well trodden route via GA,Taxi,TP to big jet and all are suffering because of it. Ex MIL and ancient BA cadetships are a red herring to the argument as they were always there as a minority and acted as the 'grammer school' of aviation since they were a nil outlay entry to the industry selected on ability.
I am pretty certain the PTF glut is coming to an end as credit/money tightens, airlines are becoming a bit more shy of employing cadets for various reasons and maybe one or two FTO's will go to the wall. My own company has even sponsored some cadets on a well financed scheme which see's them go thru the TP years as well as basic training, so there is hope for the future.
What I will be glad to be rid of, is the attitude of entitlement expressed by some (but not all, by any means) cadets. Its a byproduct of the times, but it is most unwelcome on the flight deck.
