Competition between friends/allies in zero-sum "games": Ethical? Hey all, In the context of friendships and alliances between countries; will the competition between friends/allies in zero-sum games be unethical? e.g. applying for a one-spot job at some company, two allied countries compete for a rare natural resource at one tiny place in Antarctica..etc, or two young kids compete for what TV channel to be viewed at the only TV in their house. (perhaps these are not perfectly zero-sum situations, but they can be in some cases and/or contexts) What are the deciding factors in such similar cases between what is ethical and what is not?
