Marx asserted that real freedom of expression could only be realized in a future society in which economic power would no longer destroy the essence of formal freedoms. He thus believed that formal freedom of the press, though clearly preferable to censorship, was seriously undermined by the concentration of economic power within society. There was, therefore, limited value in having the right to express ideas without the practical means to do so. Marx argued that those who owned the material means of production also owned the means of producing ideas. The fate of his own writings during his lifetime confirmed this belief, for he often found the production and distribution of his ideas restricted by his lack of money. In addition, he often found his writings suppressed by hostile governments.
