Basically what the title says. Business and Economics have since been an integral portion of higher education. I mean, just look up websites of famous and prestigious universities such as NYU, Harvard, UPenn, Cornell, etc. and look how big their business schools are, etc.
Yet I have seen that in no core curricula is either business or economics listed as one. I have seen those with included Physics, Chemistry, Maths, History all from middle school for example, yet why is that for a field this expansive in terms of enrolled scholars did preparation only start at high school, and not even as a core subject?
