must yield, and adaptation will take place, but only after much ruin. “Producers will not withdraw from that industry entirely, and their numbers will diminish only when some of the workshops have failed and a number of workmen have died of misery.” “Let us beware,” says he in conclusion, “of this dangerous theory of equilibrium which is supposed to be automatically established. A certain kind of equilibrium, it is true, is re-established in the long run, but it is only after a frightful amount of suffering.”[389] The dictum which was to some extent true in Sismondi’s day controls the policy of every trust and _Kartel_ of the present day. Nowadays production chiefly grows as the result of the multiplication of machinery, and Sismondi’s most telling attacks were directed against machinery. Consequently he has been regarded as a reactionary and treated as an ignoramus, and for half a century was refused a place among the economists. On the question of machinery the Classical writers were unanimous.[390] Machinery they considered to be very beneficial, furnishing commodities at reduced rates and setting free a portion of the consumer’s revenue, which accordingly meant an increased demand for other products and employment for those dismissed as a result of this introduction. Sismondi does not deny that theoretically equilibrium is in the long run re-established. “Every new product must in the long run give rise to some fresh consumption. But let us examine things as they really are. Let us desist from our habit of making abstraction of time and place. Let us take some account of the obstacles and the friction of the social mechanism. And what do we see? The immediate effect of machinery is to throw some of the workers out of employment, to increase the competition of others, and so to lower the wages of all. This results in diminished consumption and a slackening of demand. Far from being always beneficial, machinery produces useful results only when its introduction is preceded by an increased revenue, and consequently by the possibility of giving new work to those displaced. No one will deny the advantage of substituting a machine for a man, provided that man can obtain employment elsewhere.”[391] Neither Ricardo nor Say denies this; they affirmed that the effect of machinery is just to create some part of this demand for labour. But Sismondi’s argument is vitiated by the same false idea that, as we have seen above, made him admit the possibility of general over-production—the idea that increased production, if it is going to be useful, must always be preceded by increased demand. He was unwilling to admit that the growth of production itself created this demand. On the other hand, what is true in Sismondi’s attitude—and we cannot insist too much on this—is the protest he makes against the indifference of the Classical school in the face of the evils of these periods of transition.
