In the field to which it is applicable, namely, that of more or less unspecialised labour in large establishments, Professor Carver's theory violates some of the most fundamental conceptions of justice and humanity. He admits that it takes no account of the labourer's efforts, sacrifices, or needs, and that when unskilled labour becomes too plentiful, the value of the product may fall below the cost of supporting a decent standard of living. While he looks with some sympathy upon the demand for a minimum wage of two dollars per day, he contends that unless the labourer really _earns_ that amount, some other man will be paid less than he earns, "which would be unjust." To "earn" two dollars a day means, in Professor Carver's terminology, to add that much value to the product of the establishment in which the labourer is employed; for this is the measure of the labourer's productivity. If all the men who are now getting less than two dollars a day are receiving the full value of their product, and if all the other workers are likewise given the full value of their product, an increase in the remuneration of the former will mean a deduction from the compensation of the latter. These conclusions of ethical pessimism are extremely vulnerable. As we have shown in chapter xvi, efforts, sacrifices, and needs are superior to productivity as claims to reward, and must be given due consideration in any just scheme of distribution. Professor Carver would leave them out of account entirely. In the second place, it is not always nor necessarily ever true that to raise the wages of the poorest paid labourers will mean to lower the remuneration of those who are better paid. Many workers, particularly women, are now receiving less than the measure of their "productivity," less than they "earn," less than their worth to the employer, less than he would be willing to pay rather than go without their services. Professor Carver would, of course, not deny that the wages of all such labourers could be raised without affecting the remuneration of other workers. Even when the poorest paid class is receiving all that its members are at present worth to the employer, an increase in their compensation would not necessarily come out of the fund available for the better paid. It could be deducted from excessive profits and interest; for we know well that in many industries competition does not automatically keep down these shares to the minimum necessary to retain the services of business ability and capital. It could be provided to some extent out of the enlarged product that would result from improvements in the productive process, and from the increased efficiency of those workers whose wages had been raised. Finally, the increased remuneration could be derived from increased prices. When we speak of the unskilled labourer as getting all that he produces, or all that he earns, we refer not to his concrete product, but to the value of that product,
