Back in day "major" appliances or white goods were just that; things designed to last.
Whereas appliances of old (that were largely mechanical in nature) lasted 20-30 years or longer. Today's modern appliances on average last only 10-15 years. All those added bells and whistles including motherboards, electronics and so forth add functionally I suppose, but at cost of durability. Once they go and appliance is out of warranty it rarely makes sense economically to repair.
This goes long way in explaining why fleaPay, CL and other online are full of older appliances from 1960's through say 1980's that are still perfectly operational. Whereas you have modern stuff barely ten years old falling apart and or otherwise busted.
People will say modern fridges, dishwashers, washing machines, etc... use less energy than in past, so there is that. But if one has to replace things after just say fifteen years how much is really being saved?
