Misleading, dishonest marketing and bribed reviewers make it impossible for a consumer to know that a high quality product is indeed high quality without trying it before (which is often impractical)
Whatever you do to differentiate yourself will be copied by 728934712 Chinese brands which will flood the search results of whatever marketplace you're selling on, at all price points (even though they're the same product for the most part).
Faced with no reliable way to find the high quality needle in the haystack people just opt to buy the cheapest one, that way even if you know you're getting trash, at least it's cheap trash.
The only way that used to work to sell quality products was to create a brand and slowly build up trust by consistently selling high quality stuff but in the current "value extraction above anything else" climate, apparently that isn't profitable enough anymore, so pointy haired MBA types will happily destroy that quality for a few bucks.
