The superfluous wealth of rich countries should be placed at the service of poor nations. The rule, which up to now held good for the benefit of those nearest to us, must today be applied to all the needy of this world. Besides, the rich will be the first to benefit as a result. Otherwise their continued greed will certainly call down upon them the judgment of God and the wrath of the poor, with consequences no one can foretell.
