I remember some exercises in class (elementary school) where we learned how to count money and write a check. I don't recall any classes explaining how interest, credit, or investments work - which IMO should have been (should be) mandatory around maybe the Jr/Sr high year.
There are a few more "real life" classes I think should be taught in school, since so many parents fail to teach it to their kids. I guess there was "Home Ec", but all I ever heard about that class was girls baking cookies and knitting sweaters in it. A couple guys took the class, but for the most part it was presented as an all female class. I wasn't interested in knitting and baking, so I took stuff like the small engines shop class instead.
I wish they'd have had a class that presented a timeline of major household expense costs (home, mortgage rates, autos, insurance, utilities, food, etc...) with historical costs. Figured inflation, and presented a future timeline of estimated costs we could expect as we go through our lives. Including salary information for certain professions, as well as instruction on what education is needed (ROI of education cost vs avg. salary) and how to network with professionals and work towards advancing your career once you land the job.
So much of this stuff seems to be trial by fire. Here, we'll teach you how to read, write, and do math, but after that you're on your own! Good Luck!
We can do better, IMO.
