:::Most teens I've met (and I'll concede that I haven't yet taught 145), don't ''care'' about opportunity cost, (the same reason you objected to 6-7). That said, I agree that opportunity cost is a great life lesson, but also that some things are more important than money, (spending time with family even though you can be earning $$$).
