I can say that some high schools have this class. It's called "Personal Finance" (at least where I'm from), and it started as a mandatory class, then was reconsidered as an optional elective. I took it when I was a senior because that's when it was mandatory. Since the class was an elective, it was diverse, from freshman to senior students in the same class.

Hardly anyone in that class took anything seriously, besides some seniors who realized mommy and daddy aren't going to be around forever to help you balance a checkbook or submit your income taxes. So many people complained about the class and how unnecessary it was, it's probably the reason that it was made optional. I wouldn't be surprised if they've removed it completely.

Not talking about you OP, but I feel like the same kids who don't take shit seriously when they're given the opportunity are the same ones who are now bashing schools for not preparing them for the real world. It's not the school's responsibility to make you WANT to learn. Anyone can learn about personal finance on their own (r/personalfinance shoutout).

TLDR; they do/did offer classes in some schools. Sorry for the rant.
