Re: Elephant in the room
There's also the fact that, as designs progress through their lifecycle, value engineers have a better and better understanding of just how little is needed to meet a particular spec. That means that all of that excess value gets trimmed away. It's the same effect as "they don't make things like they used to". No, they don't, because they have a much better understanding of exactly how little is needed to meet a particular spec, leaving no excess margin for things like extra longetivity or resilience to stress. But that's progress.
