"Money is a guarantee that we may have what we want in the future. Though we need nothing at the moment it insures the possibility of satisfying a new desire when it arises."

Condemning class struggle does not mean condemning every possible form of social conflict. Such conflicts inevitably arise and Christians must often take a position in the "struggle for social justice." What is condemned is "total war," which has no respect for the dignity of others (and consequently of oneself). It excludes reasonable compromise, does not pursue the common good but the good of a group, and sets out to destroy whatever stands in its way.

— Pope John Paul II
