Socialism as Solzhenitsyn and Pope Pius XI saw it: deception; denial; danger; death. And it's cure.

Aleksandr Solzhenitsyn observed:

Modern society is hypnotized by socialism. It is prevented by socialism from seeing the mortal danger it is in. And one of the greatest dangers of all is that you have lost all sense of danger, you cannot even see where it's coming from as it moves swiftly towards you.

and this:

I hope that no one present will suspect me of offering my personal criticism of the Western system to present socialism as an alternative. Having experienced applied socialism in a country where the alternative has been realized, I certainly will not speak for it. The well-known Soviet mathematician Shafarevich, a member of the Soviet Academy of Science, has written a brilliant book under the title Socialism; it is a profound analysis showing that socialism of any type and shade leads to a total destruction of the human spirit and to a leveling of mankind into death. - A World Split Apart, delivered 8 June 1978, Harvard University

and, having survived that diabolical political system, this:

You must understand, the leading Bolsheviks who took over Russia were not Russians. They hated Russians. They hated Christians. Driven by ethnic hatred they tortured and slaughtered millions of Russians without a shred of human remorse. It cannot be overstated. Bolshevism committed the greatest human slaughter of all time. The fact that most of the world is ignorant and uncaring about this enormous crime is proof that the global media is in the hands of the perpetrators.

To complement Solzhenitsyn's insights, a few lines from Quadragesimo Anno, encyclical of Pope Pius XI on the reconstruction of the social order, issued on the 40th anniversary of Pope Leo XIII's Rerum Novarum.

10. You know, Venerable Brethren and Beloved Children, and understand full well the wonderful teaching which has made the Encyclical, On the Condition of Workers, illustrious forever. The Supreme Pastor (Leo XIII) in this Letter, grieving that so large a portion of mankind should "live undeservedly in miserable and wretched conditions," took it upon himself with great courage to defend "the cause of the workers whom the present age had handed over, each alone and defenseless, to the inhumanity of employers and the unbridled greed of competitors." He sought no help from either Liberalism or Socialism, for the one had proved that it was utterly unable to solve the social problem aright, and the other, proposing a remedy far worse than the evil itself, would have plunged human society into great dangers.

117 We make this pronouncement: Whether considered as a doctrine, or an historical fact, or a movement, Socialism, if it remains truly Socialism, even after it has yielded to truth and justice on the points which we have mentioned, cannot be reconciled with the teachings of the Catholic Church because its concept of society itself is utterly foreign to Christian truth.

119 Society, therefore, as Socialism conceives it, can on the one hand neither exist nor be thought of without an obviously excessive use of force; on the other hand, it fosters a liberty no less false, since there is no place in it for true social authority, which rests not on temporal and material advantages but descends from God alone, the Creator and last end of all things.

120. If Socialism, like all errors, contains some truth (which, moreover, the Supreme Pontiffs have never denied), it is based nevertheless on a theory of human society peculiar to itself and irreconcilable with true Christianity. Religious socialism, Christian socialism, are contradictory terms; no one can be at the same time a good Catholic and a true socialist.

To conclude, Pope Pius XI who quotes Pope Leo XIII:

129. "Wherefore," to use the words of Our Predecessor, "if human society is to be healed, only a return to Christian life and institutions will heal it." For this alone can provide effective remedy for that excessive care for passing things that is the origin of all vices; and this alone can draw away men's eyes, fascinated by and wholly fixed on the changing things of the world, and raise them toward Heaven. Who would deny that human society is in most urgent need of this cure now?
