a zero-sum game

JOURNALISM
If a situation is a zero-sum game, the advantage that one person gains from it must have an equal disadvantage for someone else. The idea that foreign investment is a zero-sum game — that one country's gain is another's loss — is mistaken. Note: Other nouns are sometimes used instead of game. According to Reed, employee benefits are a zero-sum gain. If costs for one benefit rise, it's often at the expense of another, such as paid vacation and health insurance. Note: A zero-sum game is one in which the winnings and losses of all the players add up to zero.
