Actually, what i was trying to say was that the story is advantagious to the other party too. No one can live without stories imho, so providing one that helps them jump the existential gap they've encountered (business problems are existential gaps for businesses) helps them. The story could be potentially harmfull, and you never know if it will be. Telling your kids "x is the way to look at the world" they my get into trouble due to that believe later. But i'm usually trying to make sure that at least my intent is that both parties benefit and that the story is one that adds perspective to someones life/business rather than limits theirs. I don't sell "buy this or be a hearthless mother" or "buy this and chicks will dig you" kind of stuff.
A world without marketing, a world based on non-subjectivity would be terrible imho. Humans are pieces of shit, but still they're beautifull. That's the truth, both statements are equally true (as are all perspectives on that scale). I rather live in a world of beautifull illusions than of horrifying "truths" (since those truths, even your assesment of the world as non equitable and non-productive are illusions).
Telling stories is hard work, the aim is always to both tell a good story and deliver good service/products. If one of the two fails the exchange doesn't take place and both parties are worse off. In that sense, although you're right that telling stories can be harmfull, so can be not telling a story.
It's ultimately a matter of perspective, You seem to hold high standards of rationality on meta level. Most people aren't rational, and rightly so. Rationality itself is not rational, it's much better for an individual to believe in stuff (for example, relgious people recover faster from bodily harm on avarage due to optimism). I myself found that the less rational (non socionics) I become the more happy I am; measuring human endeavors in terms of "productivity" and or "efficiency" or even "consistency" seems like measuring the color of the clowds with a tape measure.
I feel kinship with your thoughts on meta level, especially the remark about stories shaping stories (and their concequences and values) is close to how I look at the world. Ultimately you still believe in changing the world for the better, while i've become jaded (sort of) and accept the world as it is. (That is, I think that stories are a necessary evil, and can be either tedious or beautifull and thus I try to live the beautifull ones).
A fair warning; if you stare into the abyss the abyss stares back into you. A world without illusions, to me, presented (hah!) itself as a bottemless black chasm, not a new paradise of kindness and tender beauty :'(
I hope the world treats you kindly
