Have you ever wondered...

I was thinking about an economics syllabus for "average" school students, because I've done ones for top students and for uni students several times.

I haven't worked out the answers but I was thinking of just asking the following questions:

1. Why is this year's TV bigger, better and cheaper than last year's?
2. Why is food cheaper in Asia?
3. Why is Bill Gates the world's richest man?
4. Who pays for pollution?
5. How much is information worth?
