Tbh, lots of non-overpriced products that I really like tend to disappear or be hard to find, so I just learned to settle for (a) a healthy enough cheap enough alternative that is never close to being as enjoyable but "whatever, it works", or (b) an X times more expensive quasi-luxury-class equivalent that has similar qualities and is from a common enough quasi-luxury-class producer with big market presence.
But there's a second avenue of though to explore: some people care for the qualities of the product itself, and some might argue that these kinds of people (we?) are a minority, most follow trends, either marketing phabricated or grass-roots word-of-mouth trends, so if a good quality products fails to be trendy, it will have horrible economical performance at least compared to the expectations set for such a product (R&D spent and all), so has higher chances to get pulled off than a bad performing low end products, that will stick around for more, and might by sheer luck "catch a trend" at some point.
Personalized production is what will save us in the end I guess, but when it reaches mainstream will also coincide with most people becoming jobless, so I don't know how the quality of goods and life will look like overall then, can't find my crystal ball :) (I guess the utopian scenario would be that anything mass-produced even decent quality is dirt cheap by then and affordable on UBI, and all the made-to-order-by-robots will be the various degrees of luxury - white sneakers? 0.01$ same model but factory made with dotted texture on violet gradient and printed with the face of your cat? 1000.00$, and hand-customized post-factory might be the new mid-class as human labour could become cheap again?)
