Why should states matter and how do relations between fellow-citizens affect what is owed to distant strangers? How, if at all, can demanding egalitarian principles inform political action in the real world? This book proposes a novel solution through the concept of avant-garde political agency. Ypi grounds egalitarian principles on claims arising from conflicts over the distribution of global positional goods, and illustrates the role of avant-garde agents in shaping these conflicts and promoting democratic political transformations in response to them. Against statists, she defends the global scope of equality, and derives remedial cosmopolitan principles from global responsibilities to relieve absolute deprivation. Against cosmopolitans, she shows that associative political relations play an essential role and that blanket condemnation of the state is unnecessary and ill-directed.
