I think it's something to do with social status. The bigger, the more desirable, the rarer, the higher the status. Everyone wants to be the one to have something more desirable that others don't have.
Unfortunately that's how we humans work. Ever heard two people talk. Wow, have you seen his wife, she's so attractive, he must be something special.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
