Mariano Sigman : Why we don't cooperate (transcript)
Summary
The speech was spoken in Spanish but I understood that it's wrong not to listen to and not to watch it because I didn't know about Spanish. The speech uses pictures, the speaker's eyes and gestures were important, and the reflection of audiences was honest. Somehow, the same response appeared this time.
People have been made to realize that they were stereotypes. You know that happiness is not fixed, right? When your happiness is 90 percent, my happiness is not 10 percent. This is a simple thing though people thought that this was Zero-sum games. You think that someone wins 80 and thus you are left with 20 points. 
We have this fallacy and thus we don't cooperate. Our future, jobs, motivation and several solutions must be infinite.
Competition is not bad. We have to go forward with a new competition to change the world.
