Not that this is me - if nothing else, you probably can't get my mom into an aircraft even at gunpoint - but it is more like the question that wants to be considered here.
Who attends those private flight schools? Unaffordable aircraft obviously won't improve things and seem quite likely to make things worse.
If I recall correctly, Patrick "Ask the Pilot" Smith has had some things to say based on his own experience here. In any case, whether or not that model is actively used today, I would be entirely unsurprised to see it spread widely in the next couple of decades, and maybe not only in the airline industry.
At some point the pilot shortage might get severe enough that airlines have to hire pilot trainees with little or no experience and then pay them to go through a training program. So far that hasn't been necessary but it's a common model in other countries.
I suppose the larger discussion is properly around the vast increase in income inequality over recent decades, and I'd have done well to contextualize it there before now.
(In my defense, I've had such a day that the early root canal appointment, which played out like something from Marathon Man - not that my dentist is less than excellent, but I'm glad I already knew that because we had about half an hour there during which the least surprising thing in the world would have been for him to ask me "is it safe?" - that was the second most significant thing to happen since the sun last rose. So it's quite possible I am bringing less than my best to this discussion that I'm using to help me wind down toward sleep.)
