Mater et Magistra §55

⁵⁵ But however extensive and far-reaching the influence of the State on the economy may be, it must never be exerted to the extent of depriving the individual citizen of his freedom of action. It must rather augment his freedom while effectively guaranteeing the protection of his essential personal rights. Among these is a man's right and duty to be primarily responsible for his own upkeep and that of his family. Hence every economic system must permit and facilitate the free development of productive activity.
