There are fundamentals of finance, too, though. You should know how supply & demand work, how markets work, how interest rates work, how profit & loss work, and how different capital structures (stocks, bonds, etc.) allocate profits to different people.

I don't think it's important for kids to learn about specific financial products like savings accounts, CDs, different categories of stocks, etc. That all changes by the time they get into the working world anyway. But just knowing how debt & compound interest works would save many young adults from mistakes that cost them decades of their life.
