Money is a concept entire constructed by Humankind, but it is actually nothing but a notion which requires faith and trust across the board. However, uniquely, it is of enduring and compelling interest to us all and its influence exceeds that of Gods or Kings by a country mile. I notice that regardless of beliefs across the globe, including anarchic terrorist types, religious fanatics et al, virtually ALL of us accept in and believe in the concept of money (as distinct from necessarily liking its value or its necessity). On that we can all agree, which is a starting point, I guess.
