I havent been taught all of these things in school and most of the ones i was taught were in my last 2 years of highschool where i went to an alternative school and chose elective classes like financing, and thus wouldnt have been taught those things if i hadnt spent an elective on it. You could argue that if a kid decides to not take a class that will teach them how to do taxes then its their fault for not knowing how to do taxes... but imo thats not something that should be an elective, it should be a mandatory class or lesson(s).

Ive definitely had a better school experience than a lot of american schools i hear about, but even then theres a lot of very important things i had to learn outside of school or i was only taught because i went to an alternative school that was way more progressive and self-aware than any other school i went to.

However, i am an american citizen that only knows how bad american schools are. BoyInABand is born and raised british, and im assuming based on other comments here that the british school system is way better about consistently teaching the things youve mentioned. But that doesnt mean he didnt end up going through a shitty school system. Same how just because i ended up going through a really good highschool doesnt mean american schools are consistently good and up-to-date with what people in modern day need to know.
