Yes, Hollywood films have played a huge role. Go back and read where i said, "they both have their reasons". But, yeah, flippers play a role. That's kinda the idea behind flipping. Some just like to fish more than others. Collectors are to "blame" as well, so I'm certainly not discriminating here.
Heard mentality? Yep, i agree with that too.
But my main dispute was against your comparison between stocks and comics. The differences are so significant that they demand the prevention of blanket statements that would clump them together.
