"Since it is to the advantage of the wage-payer to pay as little as possible, even well-paid labor will have no more than what is regarded in a particular society as the reasonable level of subsistence. The lower ranks of labor will commonly have less, and if public relief were afforded even up to the wage-level of the lowest ranks of labor, that relief would compete in the labor market; check or dry up the supply of wage-labor. It would tend to render the performance of work by the wage-earner redundant."
