Haha! I guarantee she'll be calling you uncle nobhead!! Most 18 year old don't give a fuck about compound interest and capital gains tax, she probably just wants to know who your favourite Melbourne Housewife is... :-)A long held argument of mine. My niece left school at 18 with a shit load of A levels. I asked her what compound interest was, she had no idea. I asked here the difference between capital gains tax and income tax, she was struggling, I asked her what endowment meant, No idea. Not her fault of course.
Agree that more life skills need to be introduced to schools though, no arguments there.
