Like in any other school subject, it’s good to know how knowledge can be put to practical use in real life: how contraception works is part of biology lessons, and how to write a job application is taught in German. But there’s no need to go as far as making the school subject of economics nothing more than a “self-help” course.
And what about the claim I mentioned earlier that economics lessons might be misused as an ideological vehicle? It is beyond doubt that there are different strands of thinking in economics, just as there are in any other field of knowledge.
