III. The third argument adduced in favor of an obligation on the part of the Consuming Class is, that the purchase of articles made under unjust conditions is co-operation in the injustice. It makes no difference whether or not the employers are formally guilty of injustice. They may be forced by the competitive system, as many contend, to underpay their workmen. Nevertheless, material injustice at least is committed, and the Consuming Class have no right to co-operate formally in what may be merely material injustice for another. Yet the Consuming Class by buying goods made under unjust conditions does co-operate, it is alleged, in three ways: (A) as the recipient of the result of the injustice; (B) by furnishing the means for the act; (C) and by counselling the action. "For a co-operator is one who at the same time with another is the cause of the injury, whether secondary or equally principal, whether positive or negative. For there is not the same manner of co-operation in all cases, but this is common to all, that one person should concur with another to commit an injury."[15] (A) One of the ways of positively co-operating with an injustice, is by receiving the results of the injustice. Thus a thief will not steal a bulky piece of silver unless he has a fence to receive it, and the fence becomes guilty of the theft by receiving the article. So a business man will not manufacture an article and thus commit an injustice against the laborers whom he underpays, unless he is reasonably sure some one will receive this article after it is made. The persons who receive it, then, or the purchasers, it is argued, are in the position of the thief's fence: They are receiving an article that was obtained by injustice; and it matters not whether the article was stolen outright or the injustice committed in a more gentlemanly way. Nor does the fact of the manufacturer committing the injustice to increase his profits, rather than (as has been shown elsewhere) to meet a demand for cheapness on the part of the Consuming Class, alter the situation. For a thief steals for his own enrichment, not for the advantage of the recipient of the stolen goods.[16]
