Most theorists agree that a theory of justice ought to be practical. Janna Thompson argues that there is no theory of global justice that is both morally adequate and realistic. Those that are adequate as far as their moral content is concerned are unrealistic, and those that are realistic do not satisfy our moral intuitions. Most fail both requirements. This doesn't mean that we should give up on the very idea of global justice, but it will affect how we approach the subject - both theoretically and practically.
