To put in blunt terms, the difference is between science and social science.

In economics the outcomes are always modeled with one or few input variables: something went up/down because something else went up/down etc reality is rarely so trivial or well understood. Add that with the ability to impact geopolitics you get schools of thought and cult like following.

Nobody outside of theoretical physics cares about rivalry between string theory and loop quantum gravity perhaps not many within. However lot of people care about their economic schools of thought and it standing in academia/public discourse, as many regulatory/ political decisions are made (justified at-least) with some economic/sociological theory or other.
