Depends on what kind of fridge you buy. If you buy one for the price of a fridge in the "good old times" that doesn't come loaded with useless features, they last just fine.
A lot of degrading quality in household appliances is the result of consumers buying the cheapest products that'll get the job done. Many people would rather risk having to buy two €600 fridges rather than buying one €1200 fridge (freezer sold separately of course).
I can get a full fridge+freezer combination delivered to my home for €380. Of course that won't last as long as the €1200 equivalent from forty years ago, back when that was the normal price for a fridge.
