@ FunkyTown: Okay - now tell us the right answer. I've been thinking about it since yesterday, and have even edited my last post in this thread, because I thought my answer was wrong. It's quite unsatisfying if there were several "right" answers possible. Is it really a riddle? I mean, if there can no specific answer be given on the question, is it really a serious riddle, then? I have seen many riddles with only one right answer, so that you could say "That's it, that's the right answer!". But here? What's the right answer? And why were you sparked to remember it by a recent discussion just on world economics? I mean, where is the connection, the link between? That's also a riddle.
