Practically all evils that we face today can in some way be attributed to the principle
of "making others fail in order to win".
Alfie Kohn describes the principle of competition as
"I can only win, if you loose", mentioning examples like golf or bowling.
He describes the more extreme form of this as
"I can only win, if I make you loose", mentioning examples like tennis and war.
At least in that description I do agree with Alfie Kohn, that competition is aggression.
