My high school had a Home Economics class that did, in fact, teach some basic economics. It wasn't how to bake a loaf of bread or whatever like a lot of other schools.
We learned things like:
1. Compound Interest and how it relates to investment for retirement.
2. How much a 30 year mortgage really costs.
3. How to budget.
4. How to eat healthily on $5 a day.
5. How insurance works.
I've rarely come across other people that had this kind of a class in their high school. It's weird to me that people are graduating high school when they're supposed to be fully functional, legal adults, ready to live an adult life, and they can't even track their own spending habits - but that's what the schools are churning out. Older children with no life skills.
Parents: Home school your kids, or at least supplement their public/private schooling with some stuff that actually matters. I know, I know, it means you have to spend time with your kids and actually be a parent, not a friend.
