That he did.
Marx got it backwards though (most likely on purpose).
Communism and Socialism grew out of the feudal system and monarchy. A great example of that is France. They never recovered from their revolutions after the fall of the House of Bourbon and Napolean. Another example is China...
Jean-Jacques Rousseau advocated the noble savage idea - - a return to primitivism. He was really the father of Marxism. (Note the neo-Pagan primitivism of the Left.)
Thomas Hobbes, and the later John Locke, are philosophers who built upon philosophical ideals from Mosaic Law that are the basis for Modern Western Civilization. Rousseau establishes a philosophical basis for Marxism.
The rhetoric of Marxists in politics often use the idea of a social contract (which is stolen from Rousseau) and the term itself to promote the quasi-religious ideals they worship. Marxists, in a sense, worship the ideals of a dead Karl Marx like some Christians worship the image of a dead Jesus. The political Left often holds to the view of Rousseau, cited above. They eschew the advancement of science and of the arts. It is no wonder that in their pursuit to dominate academia, that the decline of education in the West has been a victim of the political Left. Is it any wonder that the modern Left opposes U.S. military action in the war against terrorism, hates the Jews and Israel, as well as supports the Palestinians and terrorism?
The proliferation of psychics, seers, soothsayers, healers, gurus, UFO cults, conspiracy cults, witches, etc., etc., ad nausea, is a social psychosis, an occulted (or masked) promotion of Leftist propaganda.

Marxist these days don't want to be called Marxist just like many liberals don't like being called liberal. That doesn't change what they are.
They wear a mask much like the actors of ancient Greek drama. A well-placed Marxist will not generally make the open, identifying proclamation, they are of an occult nature.
Marxism and the numerous forms of Cultural Marxism is a religion, a collection of cults. In many cases they worship a dead Karl Marx like some (and I stress some) Christians worship a dead Jesus, and not a living God. This is no more apparent than in the practice of enshrinement and regular grooming of Lenins corpse in the former Soviet Union, the use of Princess Diana, Martin Luther King Jr. and other dead people. A Golden Calf.
Like the necromancy of the late Senator Wellstones funeral rally, or "funerally" (see the Steven Plaut article, The Rise Of Tikkun Olam Paganism, Arutz Sheva: December 27, 2002; in reference to the Wellstone brand of Judaism), the use of Martin Luther King Day, or constantly invoking the "spirit of the 60s," the Left attempts to raise spirits of the dead as a totem for worship.
New Age induces a benevolent relaxation that may be disabling in the face of aggression. In a world of terrorism, New Agers can only take to the hills and leave their scriptures in jars at Esalen.(Camille Paglia,Cults and Cosmic Consciousness: Religious Vision in the American 1960s, 10:1)
It is no coincidence Islamic pagans hate Israel, Jews, Christians and Western Civilization. The entire basis of Western Civilization is Mosaic Law, something both the Neo-Pagan Left and the pagan Islamic thugs cannot abide and wish to destroy.
Read some of the interviews that have been done with Bin Laden (ABC News interview with Osama Bin Laden). Compare it to the recommended rhetoric for Marxists to use to help bring about their revolution (Marxists.org).
