You're talking about morality, theology, and economics, not just philosophy.
I agree there's that catch-22 about following the herd. Philosophers and creators in general seem to have their insights when they stand apart from the herd to gain an outsider's perspective.
Scientists and engineers don't have to worry about convincing the herd, because the technological applications of their ideas change society regardless of what the herd thinks. Philosophers and artists offer only fresh perspectives for interpreting the facts of life.
