The 30 year number is a bit disingenuous, appliances are conking out in 3-5 years which is why this is a conversation at all. In that time frame, innovation in most appliances is frivolous extras. Nothing fundamental about toasters has changed in decades. Fridges are adding TVs on the front because fridges are all the same technology and it's impossible to differentiate.
30 years for sure, that is a totally reasonable amount of time for an appliance to last. If it genuinely lasted that long I bet you actually did a few repairs in there too. Living the dream, actually even 10 years would be amazing. We could cherry pick examples of long lived products but the point for me is that people don't pay for longevity like you said, but we need it for other reasons. Reduce waste, improve consumer choice and power over their own objects.
In regards to efficiency, it's definitely more efficient not to produce a society worth of new appliances ever 5 years or so. Improved repairability aldo means improved recycling of the components too.
