An important difference between economics and physics/chemistry etc in the context of this discussion is that they are once separated from societal impact. E.g., one needs the engineering professions before nuclear physics means anything concrete. In contrast, there is no such thing as an "economic systems engineer". Economists routinely, profitably, and frequently disastrously play that role.
