Are there any kids book that explain these money concepts to elementary school kids? I feel one the big failings of the school system is that these are not taught early on and instead a lot of time is spent teaching things that kids will never use in their lives.
A book I read well over 30 years ago, and is still apparently updated today, is "The Kids' Money Book" by Neale S. Godfrey, which you can certainly find secondhand for cheap. There are updated versions authored by Jamie Kyle McGillian, and so long as they are in the original vein they are probably excellent.
However it's not something I would throw at a 6-year old. A sharp 8-year old should be able to grok all of it though.
Reminds me of this excellent video https://youtu.be/HLIJkmy3vy8
it's in Spanish, he tells the story of explaining a financial system crash to his daughter. Probably has subtitles in English, I recommend it
You need to understand exponentials to really get it. Where I live, they only teach it in advanced math classes in 11th grade, so elementary school seems ambitious.
