I can't imagine what model of the world people have who think that people wouldn't want things they don't need if it weren't for advertising. This is a view I see a lot, and it baffles me how anyone could think this having met any humans or read any history. I'm not endorsing it as salutary, but it's fundamentally human to want things that are unnecessary; that restlessness is what's what's driven our history as a species, for better or for woes.
