A complete system of commerce must include a final destination point for "clearance" that serves both the needs of industry and the bottom-feeder (plecostomus). I do not use that term as an insult because it describes me quite well as a loyal customer of used record stores and bookstores. Some of my most beloved rock bands and musicians were first discovered in the dollar bins or cutout racks. It is good that others' cast-offs have found a happy home. Without such a method of filtering out the unwanted production, any retail system is incomplete or under-developed.
