If anything, the survivorship bias is in the OPPOSITE direction. People are dumping old appliances for some new shiny hotness, only to find out that it failed 4 years later and the repair will cost over half of a new machine.

Historically, appliances WERE repairable. Cars were repairable. That is the bias. The bias is for appliances that have failed and been repaired and still work in spite of a previous minor malfunction. And now, homeowners are all surprised pikachu when then new one doesnt last, and costs a fortune to try and repair or replace.

In my experience, old appliances are disposed of not because of they failed, but because people didnt want them anymore. I do home remodeling and I have pitched so many working appliances because the homeowners didnt like the way they looked, or wanted some programmable function. They worked fine. In fact , I try to make sure they find a new home because pitching old working appliances kills me inside.

I had an avocado green dryer once. I bought used for $50. It was probably 20 years old then. I used it for another 20, and sold it for the same $50 when I couldnt take it with me. Looked like shit. Ran great. I spent $35 on a new belt and rollers when they died. Took me 2 hours to fix. I have thrown out dryers in way better condition because the homeowner didnt want them. Not because of any functional problem.

How do you figure? Most things break down eventually and need repair. Older appliances were much more repairable. I have had lots of success repairing older, simpler appliances that did break and need repair.

And contrast that with some horror stories about newer appliances that are near impossible/cost prohibitive to repair. There is a clear winner for reliability and longevity. As long as you are content with older feature sets and technology, its a clear winner. I have had many appliance people tell me this as well.

The repair parts for the old machines are way cheaper and easier to repair and diagnose. Modern appliances are very difficult to fix.
