Rodbertus says outright that the only remedy for these crises is the 'complete reversal' of contemporary property-relations or a planned economy, concentrating all means of production 'in the hands of a single social authority'. To set troubled minds at rest, however, he is quick to add that he reserves judgment as to whether there can actually be such a state of affairs--'yet this would be the only possible way to prevent slumps of this kind'. Thus he expressly regards anarchy in the modern mode of production as responsible for only a specific and partial manifestation of crises. Rodbertus scornfully rejects Say-Ricardo's axiom of a natural equilibrium between consumption and production; just like Sismondi, he emphasises that everything turns on the purchasing power of society, and also takes it to be dependent upon the distribution of income. All the same, he does not endorse Sismondi's theory of crises and disagrees sharply with the conclusions drawn from it. If Sismondi saw the source of all evil in the unlimited expansion of production without regard to the limitations of incomes, and advocated a restriction of production, Rodbertus, quite on the contrary, champions the most powerful and unrestricted expansion of production, of wealth and of the productive forces, believing this to be a social necessity. Whoever rejects the wealth of society, rejects at the same time its power, its progress, and, with its progress, its virtues. Whoever stands in the way of growing wealth, stands in the way of all social progress whatever. Every increase in knowledge, resolve and capacity is conceived as bound up with an increase in wealth.[254] From this point of view, Rodbertus is strongly in favour of issuing houses which he regards as the indispensable foundations for a rapid and unrestricted expansion of company promoting. Both his essay of 1859 on the mortgage problem and the treatise on the _Financial Crisis in Prussia_[255] are devoted to this plea. He even polemises outright against the Sismondian type of _caveat_, as usual broaching the matter first from his peculiar Utopian ethics.
