Not that sure. I know Bosch, Liebherr and Samsung fridges bought in the 2000’s that lasted 10+ years, some of them that keeps running even after being used heavily (being moved, used by families of 5…etc). They are repairable and some got repaired. They are 2-3000€+. Which is 2-3x the average monthly salary.
An other thing to account for is the price of repairs. If your appliances costs less than one hour of a mid-skill technician, it’s hard to justify the spending. Same for doing it yourself if you’re time is worth a lot. The only solution is to by high end, which is always risky and more cash intensive. Most people will prefer buying cheap and change to new if required
You start by saying "not that sure" but then continue to support my point. So now I'm also not that sure what you mean.
3000€+ in the early 2000s is easily 5000€ today accounting for inflation. Even if you mean they are 3000€ today, at that price point the market is needle thin. The best selling fridges on Amazon.de right now are in the 300€ region, maybe 500-600€ if you want to go "premium". So you're saying a fridge that's 10-15 times more expensive than the cheap best sellers is also better.
This is exactly the quality/price trap. People remember the quality from "way back when" but forget the price. We mostly just traded quality/longevity for cheaper and faster replacement. Quality didn't necessarily go down, it's just people target cheaper products today.
