People that play zero sum games only get to play with other zero sum players. There is some risk they will lose. People that play win-win games get to play with other winners (and be winners).
Be a winner.
Be a winner.
This whole win-win ideology is mostly a tool to erase where the losers are, and to make losers feel better about losing. Every increase in my paycheck is a decrease in someone else's.
Obviously the inventor of fire got more of a reward from his invention's bounty, but everyone still benefited. Similarly whoever automates your job gets most of the reward, but ideally we all benefit through cheaper products.
At least, that's how it's supposed to work. Obviously it doesn't always.
