Catechism number 1938
There exist also sinful inequalities that affect millions of men and women. These are in open contradiction of the Gospel:

Excessive economic and social disparity between individuals and peoples of the one human race is a source of scandal and militates against social justice, equity, human dignity, as well as social and international peace.44
