Excuse the smugness. Just providing counter perspective.
I know people, this does not help more people to easily understand the topic. But, lot of math like number theory was worked out as a intellectual exercise rather than application based.
Application followed theory. And people theorized for fun.
That can also make topics, abstract and unrelatable.
Things you won't end up using lack any "why" beyond "just in case". The only way you avoid using personal finance skills is if you partner up and completely offload that responsibility onto someone else. Fine, in that case, don't bother learning it!
Non native speaker here. I think I conveyed something that I did not mean to convey. I was just saying concentrating on the "why" and having a utiliterean perspective about the topics to learn while useful and help the children to relate, need not be the only criteria.
Cause, lot of things can be a little more abstract and some what removed from exact applications in real world. But, they can still be beautiful. That is what I meant to say. I think I conveyed the exact opposite.
