Ricardo's thesis in the controversy with Sismondi takes the following form: 'Supposing that 100 workers produce 1,000 sacks of corn, and 100 weavers 1,000 yards woollen fabric. Let us disregard all other products useful to man and all intermediaries between them, and consider them alone in the world. They exchange their 1,000 yards against the 1,000 sacks. Supposing that the productive power of labour has increased by a tenth owing to a successive progress of industry, the same people will exchange 1,100 yards against 1,100 sacks, and each will be better clothed and fed; new progress will make them exchange 1,200 yards for 1,200 sacks, and so on. The increase in products always only increases the enjoyment of those who produce.'[203] The great Ricardo's standards of reasoning, it must regretfully be stated, are if anything even lower than those of the Scottish arch-humbug, MacCulloch. Once again we are invited to witness a harmonious and graceful country-dance of sacks and yards--the very proportion which is to be proved, is again taken for granted. What is more, all relevant premises for the problem are simply left out. The real problem--you will recollect--the object of the controversy had been the question: who are the buyers and consumers of the surplus product that comes into being if the capitalists produce more goods than are needed for their own and their workers' consumption; if, that is to say, they capitalise part of their surplus value and use it to expand production, to increase their capital? Ricardo answers it by completely ignoring the capital increase. The picture he paints of the various stages of production is merely that of a gradually increasing productivity of labour. According to his assumptions, the same amount of labour first produces 1,000 sacks and 1,000 yards textiles, then 1,100 sacks and 1,100 yards, further 1,200 sacks and 1,200 yards, and so on, in a gracefully ascending curve. Not only that the image of a marshalled uniform progression on both sides, of conformity even in the number of objects brought to exchange, is wearisome, the expansion of capital is nowhere as much as mentioned in the model. Here we have no enlarged but simple reproduction with a greater bulk of use-values indeed, but without any increase in the value of the aggregate social product. Since only the amount of value, not the number of use-values is relevant to the exchange transaction, and this amount remains constant in the example, Ricardo makes no real advances, even though he seems to analyse the progressive expansion of production. Finally, he is quite oblivious of the relevant categories of reproduction. MacCulloch had begun by making the capitalists produce without any surplus value and live on air, but at least he recognised the existence of the workers, making provision for their consumption. Ricardo, however, does not even mention the workers; for him the distinction between variable capital and
