If you're manufacturing something that's going to go in a house... ...and that means it should be expected to last 20 years... ...then maybe just don't use the cheapest part you can, and instead actually engineer it to last 20 years? You're talking about it like the manufacturer has no choice but to make it as cheap as possible and hey, if it fails, it fails—but that's not true at all. If there were a requirement for something to be more durable, then the manufacturer would be both able and obligated to follow it. Unfortunately, I don't believe there is such a requirement as things stand.
