Supply and demand: as usual with economics, it's complicated. I taught a college class in economics for non-business majors so I do know something about it. Supply and demand works because it's a basic human behavior - the principle of scarcity. Cost is what's affected by supply and demand -the cost of something is influenced by how scarce it is. You are right that demand has been manipulated by mass marketing, but it's still demand, and if something is in short supply the price will go up.
