The 'essence of luxury-goods being that they enable the consumer to use up more capital and labour power than in the case of ordinary goods', the three entrepreneurs manage to consume by themselves in the form of laces, fashionable carriages and the like, their entire half-share in all the labour performed by the society. Now nothing unsaleable is left, and the crisis is happily avoided; over-production is made impossible once and for all, capitalists and workers alike are safe; the name of v. Kirchmann's magic cure which has brought all these benefits to pass, and which re-establishes the balance between production and consumption, being: luxury. In other words, the capitalists who do not know what to do with their surplus value which they cannot realise, are advised by the dear fellow--to eat it up! As it happens, luxury is in fact an old familiar invention of capitalist society, and still there are recurrent crises. Why is this? v. Kirchmann enlightens us: 'The answer can only be that in real life sluggish markets are entirely due to the fact that there are still _not enough_ luxuries, or, in other words, that the capitalists, i.e. those who can afford to consume, still consume too little.' This misguided abstinence of the capitalists, however, results from a bad habit which political economists have been ill-advised to encourage: the desire to save for purposes of 'productive consumption'. In other words: crises are caused by accumulation. This is v. Kirchmann's principal thesis. He proves it again by means of a touchingly simple example: 'Let us assume conditions which economists praise as more favourable,' he says, 'where the entrepreneurs say: we do not want to spend our income to the last penny in splendour and luxury, but will re-invest it productively. What does this mean? Nothing but the setting-up of all sorts of productive enterprises for delivering new goods of such a kind that their sale can yield interest (v. Kirchmann means profits) on a capital saved and invested by the three entrepreneurs from their unconsumed revenues. Accordingly, the three entrepreneurs decide to consume only the produce of a hundred workers, that is to say to restrict their luxury considerably, and to employ the labour power of the remaining 350 workers together with the capital they use for setting up new productive enterprises. The question now arises in what kind of productive enterprises these funds are to be used.' Since, according to v. Kirchmann's assumption, constant capital is not reproduced, and the entire social product consists entirely of consumer goods, 'the three entrepreneurs can only choose again between enterprises for the manufacture of ordinary goods or for that of luxuries'.
