Even IF appliances were made the same way as they were in the 60's I'd wager that they would still be replaced every 10 years or so on average. Appliances today by and large just aren't repaired like they were years ago. The consumer sees an indicator light fail and they wonder what next and they trash the machine preemptively. Add into the mix the idea of new and fresh and a lot more replacements are done needlessly (see also Stainless Steel).
A couple years ago Annette's father has the draft inducer motor in his 6 year old furnace fail. It was going to cost nearly $900 to replace it. He pondered it a while and wondered what would be next to go. Out of fear alone $6000 later a new replacement was installed for that perfectly good furnace. Funny how people fear the possible replacement cost but they will just pay it upfront when the decision is theirs.
