Surely not. And since the fruit is the product, not of the stick which brought it down, but of the tree which grew it, Rodbertus has already proved that all 'economists since Adam Smith' are grossly mistaken if they maintain that income derives from capital. After a clear exposition of all fundamental concepts of economics on the example of Robinson [Crusoe]'s 'economy', Rodbertus transfers the knowledge thus acquired first to a fictitious society 'without ownership in capital or land', that is to say to a society with a communist mode of possession, and then to a society 'with ownership in capital and land', that is to say contemporary society, and, lo and behold--all the laws of Robinson [Crusoe]'s economy apply point for point to these two forms of society as well. Rodbertus contrives here a theory of capital and income which is the very crown of his Utopian imagination. Since he has discovered that Robinson [Crusoe]'s 'capital' is the means of production pure and simple, he identifies capital with the means of production in capitalist economy as well. Thus reducing capital, with a wave of his hand, to constant capital, he protests in the name of justice and morality against the fact that the wages, the workers' means of subsistence, are also considered capital. He contends furiously against the _concept_ of variable capital, seeing in it the cause of every disaster. 'If only', he grieves, 'economists would pay attention to what I say, if only they would examine without prejudice whether they are right or I. This is the focal point of all errors about capital in the ruling system, this is the ultimate source of injustice against the working classes, in theory and practice alike.'[271] For 'justice' demands that the goods constituting the 'real wages' of the workers be counted, not as part of capital, but as belonging to the category of income. Though Rodbertus knows very well that the capitalist must regard the wages he has 'advanced' as part of his capital, just like the other part laid out on immediate means of production, yet in his opinion this applies only to individual capitals. As soon as it is a question of the social aggregate product, of reproduction as a whole, he declares the capitalist categories of production an illusion, a malicious lie and a 'wrong'. 'Capital _per se_ (properly so-called), the items which make up capital, capital from the nation's point of view, is something quite different from private capital, capital _assets_, capital _property_, all that "capital" in the modern use of the term usually stands for.'[272] An individual capitalist produces by capitalist methods, but society as a whole must produce like Robinson [Crusoe], as a collective owner employing communist methods.
