Why to you do disservice to the Marx as one of the 3 fathers of sociological science and one of the top-70 most cited scholars in the history?
That would be worth something, if Sociology and being cited would be valuable. But they are not.
It is very important to stress, that USSR was not the real socialism in the Marxian sense.
That can be taken in two ways. Either you claim that you are more competent Marxist than Soviet leaders, which, um, requires supporting evidence. Or you fail to notice that the Soviet leaders only claimed to be “building Communism”.
As a joke goes, “Is it true that Communism was going to be built by 1980?” - “Yes, but it has been decided to hold Olympic Games instead.”.
Papal criticism of socialism is essentially of Marxist socialism, not of all forms of socialism. There are many kinds of socialism, such as guild socialism and Christian socialism, that do not seek to eliminate private property, are not fundamentally atheistic, and other issues raised as inherently problematic.
On the contrary, see “Quadragesimo anno” (
http://www.vatican.va/content/pius-...s/hf_p-xi_enc_19310515_quadragesimo-anno.html), for example, “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.”.
The Catechism speaks out against both pure Communism and pure Capitalism (the free market nature of it).
See “Compendium of the Social Doctrine of the Church” (
http://www.vatican.va/roman_curia/p...ndio-dott-soc_en.html#Role of the free market), for example, “A truly competitive market is an effective instrument for attaining important objectives of justice: moderating the excessive profits of individual businesses, responding to consumers’ demands, bringing about a more efficient use and conservation of resources, rewarding entrepreneurship and innovation, making information available so that it is really possible to compare and purchase products in an atmosphere of healthy competition.”.
Free market as such is not to be rejected. It only has to be limited (“Economic activity, above all in a free market context, cannot be conducted in an institutional, juridical or political vacuum. “On the contrary, it presupposes sure guarantees of individual freedom and private property, as well as a stable currency and efficient public services”.”).
So, while it is true that Church rejects both “pure Capitalism” (as understood by Anarcho-Capitalists), and “pure Communism” (as understood by many kinds of Marxists and the like), the systems that are acceptable are going to be much more like “pure Capitalism” than like “pure Communism”.
