Divini Redemptoris §8

⁸ The Communism of today, more emphatically than similar movements in the past, conceals in itself a false messianic idea. A pseudo-ideal of justice, of equality and fraternity in labor impregnates all its doctrine and activity with a deceptive mysticism, which communicates a zealous and contagious enthusiasm to the multitudes entrapped by delusive promises. This is especially true in an age like ours, when unusual misery has resulted from the unequal distribution of the goods of this world. This pseudo-ideal is even boastfully advanced as if it were responsible for a certain economic progress. As a matter of fact, when such progress is at all real, its true causes are quite different, as for instance the intensification of industrialism in countries which were formerly almost without it, the exploitation of immense natural resources, and the use of the most brutal methods to insure the achievement of gigantic projects with a minimum of expense.
