Personally, I think there is a market for quality in appliances as well (certainly I'd look for quality over wiz bang Internet of Things crap); the appliance market just has a quasi-monopoly dominating sales, and they are currently over-focused on a race to the bottom.

In audio, it's possible to find products designed to last. My current amplifier is from Bryston, bought about 16 years ago. Their warranty for their analog products is 20 years. (http://bryston.com/pages/faq.html)
