These skyrocketing costs make it so the fleet ages and becomes less reliable. So people get out. Or they die because they can't fly enough to get experience or the aircraft has a problem because it isn't flown enough.
And costs rise further because there is no market. It's a downward spiral. And it seems that the FAA is completely happy with the situation.
I've been out on beautiful days (low 80s, calm, 10 mi vis) and the CTAF is all but dead. Even 5 years ago there would have been 2-3 in the pattern and I would have heard a steady stream of traffic around the other 5 airports in the same frequency.
