>>Most of the time, advertising is a parasite on just about everything.
I guess we need some advertizing to know what's out there. As for the rest: you're right that cynical marketers claim that more creativity and cost goes into branding/marketing than into product design these days. But they wouldn't do it if it didn't work. Just as tabloids feed the sensationalist desires of a certain audience along with firebrand politicians etc etc, branders/advertizers make their $ by feeding into a target audience's desire to be part of something cool, preferably with price being part of the barrier to entry. Unfortunately whether we like it or not is as nothing compared to billions of dollars of sales driven by branding at the expense of quality. Who cares if the shirt frays or fades as long as it has this season's cool logo? Such is life.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
