Haha yes Andrez, very good ideas there! Imagine playing them videos of speeches by Tony Blair or any dodgy politician in fact. They could watch for visible signs of shiftiness and word-spin. I reckon in today's world, youngsters need to finely tune their scam/dodginess radar. You and I could prepare a super curriculum for A-level Political/Business Awareness!
I also think they'd benefit from being asked to read the 'fine print' in various contracts, and identify the pitfalls. Sky (which we used to have years ago, but no more!) actually reserved the right (in tiny print) to raise their charges three times during the first year of the deal, and one had no say in it at all. Terrifying!
