It's like the way psychiatrists defer to society in defining mental health and illness, by taking illness to be, in part, a social dysfunction. And it's up to society at large to determine which jobs and responsibilities are proper.

By abdicating their responsibilities to think through the depth of the problems they face, given their scientistic pretensions, psychiatrists and economists can pretend to be neutral. They just go with the flow, even like Nazi soldiers just following orders. If society deems homosexuality immoral, psychiatrists follow suit and lock them up. Psychiatrists are just morally neutral, after all, even though the social problems they face obviously aren't. And if certain societies are biased towards plutocracy, because that's how capitalism works, economists will carry water for the rulers of those societies, letting that kind of society dictate the initial endowment of resources.

Then it's up to philosophers (deeper thinkers) to point out what's gone wrong in those disciplines. And here we are.
