It also depends on the culture of teaching. In econ and, to a certain extent, in comp sci the stuff occurring within universities is very different from what students of those subjects do when they leave.
And, imo, this is actually due to the popularity of the underlying subject. Both econ and comp sci are popular because of what you can do when you leave uni but this means more funding for those inside uni. This funding seems to go into producing more arcane research and increasing the complexity of the subject (not knowledge, just complexity).
Mathematics doesn't do this. The practical and the abstract are clearly demarcated. If you are studying to go onto research, there are usually specific courses. If you just need to know calc, there are different ones.
It isn't healthy when this distinction isn't clear. Economics has suffered massively from being very abstract. Comp sci is probably going the same way. And I think in both cases more effort needs to go into making the knowledge more accessible.
