"Making Sense of Global Justice: The Sufficiency Threshold" is a significant non-fiction book that engages with current theories of global justice. The author, Mario Solís, aims to defend a specific perspective on social justice that focuses on the fundamental demand that every person should have enough to lead a dignified life. In this work, the idea of the "Sufficiency Threshold" is introduced, serving as a central point for understanding global social justice. Solís argues that social justice transcends the boundaries of nation-states and that global social justice should not simply be viewed as an extended form of national social justice. The book draws on empirical findings from various social sciences to illuminate and analyze the complex interconnections of global justice.
