That's something I was taught neither by my parents, nor at any point through my schooling. It'd be great if folks had this kind of fiscal literacy; but where are we expected to gain that knowledge?
I've heard tell of "civics" courses, back in the day, that taught the basics of what adults are expected to know. But they're long gone now.
There is also this lost art or changing a tire, oil, checking fluids.
Civics wasn’t around when I was in high school but I remember my grandparents and parents had taken something similar.
When I was a child in the 2000s we literally had two weeks where the "normal" curricula went to the wayside and we did two weeks of test prep for the city and state exams. Then I show up to college and my roommates getting into the top medical schools need to be told how to fry an egg.
Yeah, but it turns out unpredictable ACH transaction delays made that harder than I had expected.
