34 We desire to touch upon another question of weighty importance, the social question, which, remaining unsolved, has been agitating States for a long time and sowing amongst the classes the seeds of hatred and mutual hostility. You know full well what aspect it assumes in America, what acrimonies, what disorders it produces. It is not necessary therefore that We dwell on these points. The fundamental point of the social question is this, that the goods created by God for all men should in the same way reach all, justice guiding and charity helping. The history of every age teaches that there were always rich and poor; that it will always be so we may gather from the unchanging tenor of human destinies. Worthy of honor are the poor who fear God because theirs is the Kingdom of Heaven and because they readily abound in spiritual graces. But the rich, if they are upright and honest, are God's dispensers and providers of this world's goods; as ministers of Divine Providence they assist the indigent through whom they often receive gifts for the soul and whose hand - so they may hope - will lead them into the eternal tabernacles.
