>> Life is not a zero-sum game. That might have been true in the past, but with 7.5 billion people on the planet we are aproaching the point when life becomes zero-sum. What I mean is that in pre-historic era the caveman that didn't get along with his tribe could just leave them, go find some uncharted territory and make a living from what he could hunt and build with his own hands. Even in Middle Ages, discovery of America was a game changer: suddenly the people that would otherwise had to live in poverty were given an opportunity to go to the New World and become rich with nothing but hard work. Nowadays, we are using so much resources that we have to compete for them. You cannot easily increase yearly supply of oil, or gas, or food, at least not on global scale. Also, in developed economies unemployment does not really exist so to find employees for your startup you need to take them out from other companies. That's makes the life more and more competitive.
