"Cooperation" has been the mantra of the Kindergarten-minded in our midst for years. "Competition" is supposedly male, leads to Capitalism and war and other not-nice things, and is thus evil and a human trait which must be eliminated.
Of course, I have never noticed women to be any less competitive than men. Everybody enjoys a bit of the spice of competition in life, even when you lose.
Competition vs Cooperation a phony duality which, I assume, comes from some wacky ideology. Case in point: The Dark side of Cooperation.
