In the past few decades, the number of scheduled flights has grown tremendously, the number of aircraft has grown, traffic has increased substantially at many major airports, fuel economy demands have become increasingly important... (which means those old aircraft aren't as viable anymore) A lot has changed, which requires new aircraft to compensate. I think all of this should be considered. Remember that the incident rate per million miles or per thousand flight hours is _down_ today compared to the imagined golden period in the past.
