Some time ago, you could buy something cheap that fails very quickly, or you could buy something expensive that lasts a long time. It used to be more cost-effective to buy the expensive thing, because during the lifetime of the expensive thing, you would have spent even more money in total replacing the cheap thing every time it failed. But as far as I can tell, this is no longer the case.
Now, it seems as though in the best case, you're spending 5× as much to buy something that will last only twice as long. It seems that now, it's actually more cost-effective to buy the cheap thing and keep replacing it. I've been hearing reports of appliances that are specifically engineered to last a little bit longer than the warranty, then reliably fail very shortly after, when the warranty is expired. Not to mention that warranties in themselves are getting shorter and shorter, covering less and less, and requiring the buyer to ship the product to the company at their own expense for the company to even decide whether to do anything.
It seems that pretty much every company that has a reputation for reliability is now using their name to sell inferior-quality products at a premium price. I've been hearing reports about multiple quality issues from new models from companies such as Miele, Speed Queen, Vitamix, BlendTec, Bosch, and many others that are often recommended in this sub; Speed Queen and BlendTec in particular have either sold to a private equity firm or gone public, which inevitably leads to steep quality decline. You will, of course, find defenders of those brands, but the things they say come across as either astroturfing or someone who has naively swallowed the marketing of those brands.
Perhaps these days, if you truly want a BIFL product, your only option is to go somewhere like Craigslist, Kijiji, or Facebook Marketplace, and hope that you can find someone selling their perfectly good older thing at a reasonable price because they found themselves not using it enough to justify keeping it, because they want the newer model with more fancy features, or because it broke in a way that's easy to fix and they just can't be bothered to do so.
To what extent am I wrong about this?
