Somebody correct me if I’m wrong, but I once heard that, apart from planned obsolescence, there are parts in modern appliances that wear out faster because the parts provide some other benefit. For example, if there are plastic parts like certain gears, they may be quieter than equivalent metal parts.
There’s a plastic gear in KitchenAid mixers that is designed to fail before a more catastrophic failure, it’s easily replaced yet still some people will get a sturdier one and then end up burning out their motor 😂
Metal geared power transmission can be designed with shear pins for a simple and cheap failure mode. Plastic is trash. Want quiet? Then use a gear profile other than straight.

You would be surprised at the things that can be repaired if you are smart, have some skills, and determination to do so.
Sadly, very few people are willing to learn new things or skills.
