I just had a thought.
I finished a book on animals yesterday, animals dont have classes right? not in the sense we use them anyway. As in, economic classes, FS was making allusions to.
But inevitably, classes ( if you can call them that) are put into affect. When animals are introduced ( lions were a prime exmple) it soon emergers who is the alpha, and the omega animal.
Dosent that too apply to humans? Although we can often get along no a similar level ( work mates, friends etc') it also often emerges who is the dominating person in a relationship, eg - the bully, the jock, the smart guy etc'.
