Just clarification on the term property from a Marxist perspective. Property gets its justification in existence by the fact that the person in the propertied class needs to enforce their grasp on it to dictate their terms with what they want to do on that property. Likewise, property, when finally entrenched and shaped in the base (base-superstructure of society), maintains the relationships to production as they further solidify the relations of the propertied and non-propertied. Further along the line, the propertied class has the mental means of production and dictates the non-propertied class consciousness. (As social being determines class consciousness to paraphrase Marx, this would be further clarified with false consciousness.) Unless class consciousness builds up, dialectically the thesis (private property) doesn't meet a serious antithesis (the non-propertied as collective property is more or less the synthesis) and contradictions between the two of them will amount to barely any struggle.
