Is there a word for that slightly scummy, uncomfortable feeling you're left with after reading a particularly empty piece of marketing drivel?
Grandiosity with expectations of superior treatment from others
Fixated on fantasies of power, success, intelligence, attractiveness, etc.
Self-perception of being unique, superior and associated with high-status people and institutions
Needing constant admiration from others
Sense of entitlement to special treatment and to obedience from others
Exploitative of others to achieve personal gain
Unwilling to empathize with others' feelings, wishes, or needs
Intensely envious of others and the belief that others are equally envious of them

The same personality defect leads to monumental fails, so people on the project only concern themselves with what they have been hired for, so if you are a writer (e.g.) and hired to be some influencer/journalist then you care about your ego as writer and not care about whether the event is going to be a viable financial concern. So the whole thing suits the build someone up and then discard way these people work.
