The solution is simple but the shareholders won’t like it: remove third party sellers.
I also wouldn't mind a marketplace that is well known to be hit or miss. When I place an order on alibaba or bangood, I know exactly the risks I'm taking. That risk, weirdly, almost makes it entertaining. "Is it going to be the ball bearings I ordered, or a pair of Crocs shoe knockoffs, or a beef jerky? Place your bets!"
I have to assume that such an option exists. There is no way in hell that Amazon execs are limited to the same search options and overall UX as ordinary users. We just don't have access to the VIP entrance.
I doubt Amazon execs use Amazon.
3rd party sellers pay them for ads. Then they pay them if a product is sold. And then they pay them for packing and shipping the product. And then they pay them if the product is returned and they don’t even get any of the money they pay Amazon back if the product is returned.
It’s no wonder Amazon is filled with sellers of fake products because any seller of legitimate products could barely survive on their marketplace with all the fees Amazon showers them with.
