zero-­sum game/competition, multiracial democracy. America is becoming less racist and yet more divided by racism

What Is a Zero-Sum Game?

Zero-sum is a situation in game theory in which one person’s gain is equivalent to another’s loss, so the net change in wealth or benefit is zero. A zero-sum game may have as few as two players or as many as millions of participants. In financial markets, options and futures are examples of zero-sum games, excluding transaction costs. For every person who gains on a contract, there is a counter-party who loses.
