Answer:
True
Step-by-step explanation:
A zero sum game happens when one player's gain is exactly the same as the other player's loss, e.g. I won $100 and my opponent lost $100. But as economics has taught us, sometimes both sides can win, i.e. a win win situation.
Real life business is not the same as sports where one side must win and the other must lose. E.g. a trade agreement between 2 countries might at first result in one country benefiting more from trade, but as time passes, things will start to balance out and both countries will start to benefit from trade. As trade increases between nations, all the nations involved will win, so the situation will be a non zero sum game.
