What if you got short changed and lost a lot of money?
Well actually there's a high possibility that might happen to me sometime during my life.
Thing is, I "was fail" at maths for my whole life, I have absolutely no affinity towards it nor any other 'exact science' and the maths teaching in primary school and first two years of high school (I'm in the philology/foreign languages class and we stop studying maths, physics, chemistry and biology in the 3rd year) was made with a very "compulsory-like" feeling to it, and I had this really great urge to be good at it as well, out of pure ambition, without actually liking it, which made it quite a major pain in the ass back in the day. It somehow feels the same way now as well, especially that I realise there was absolutely no point in trying to be in the top in a subject that isn't naturally developped in your case. So of course, I wasn't saying maths had no utility, cause it obviously does, but that at least for me, it would definitely not be a priority anymore, even if I was still forced to go back and study it.
They reintroduced the kids back into the class and before too long each one of them was better at maths than the rest of the class.
Yeah, musical theory and education is a really good tool of organizing oneself, and I personally think it's much more pleasant than picking up an actual 'science', since music has a greater range of subjects and valences and it also allows one to relax and to feel like they're doing it for their own well-being and in a more exciting way. And also, even though it might sound silly, it apparently gives one the feeling of a greater 'individualization' and gives them a greater, positive kind of ambition in succeeding to master their instrument/compositional skills.
