Abstract
Political philosophers sometimes refuse claims for global justice in the socioeconomic sphere arguing that they would create global welfare institutions if realized. However, the injustice of the global economy might result not mainly from an unequal distribution of financial resources but from an unequal distribution of the right to participate in the shaping of the global political and economic order. The paper deals, in a first step, with the question to what extent property is an indispensable requirement for freedom and autonomy in the theories of Kant and Marx. In a second step, it proposes criteria of justice appropriate to a normative assessment of the politics of international organizations.
