B-n.D.!
I believe the competative edge lies in all of us.
It is a latent savagery lying dormant in our sphyco from the time when we were still living in caves and battling each other for a share of the Hairy Mamoth kill. In terms of brain size we have only increased a tiny fraction on the evolution scale since those days.
Any sign of another person even hinting at competing with us , raises that flaw in our nature.
