As a determinant of ownership, possession is the feeblest of all factors, and yet it is of considerable importance for a large proportion of incomes and property. In the distribution of the national product, as well as in the division of the original heritage of the earth, a large part is played by the title of first occupancy. Much of the product of industry is assigned to the agents of production mainly on the basis of inculpable possession. That is; it goes to its receivers automatically, in exchange for benefits to those who hand it over, and without excessive exploitation of their needs. Just as the first arrival on a piece of land may regard it as a no-man's territory, and make it his own by the mere device of appropriation, so the capitalist may get morally valid possession of interest. Sometimes, indeed, this debatable share, this no-man's share of the product of industry, is secured in some part by the consumer of the labourer. In such cases their title to it is just as valid as the title of the capitalist, notwithstanding the doubtful titles of productivity and service which the latter has in his favour. First occupancy and possession are the more decisive factors. In the great majority of instances, however, the capitalist is the first occupant, and therefore the lawful possessor of the interest-share. The general justification of interest set forth in the immediately preceding paragraphs is supplemented in the case of the great majority of capital owners by the fact that their income from this source is relatively insignificant. The average income of the farmers of the United States is only 724 dollars per year, and of this 322 dollars is interest on the capital invested in the farm.[151] Even when we make due allowance for the high purchasing power of farm incomes, due to the lower cost of foodstuffs and house rent, the total amount of 724 dollars provides only a very moderate living. Consequently the great majority of farmers can regard the interest that they receive as a necessary part of the remuneration that is fairly due them on account of their labour, sacrifices, and risks. So far as they are concerned, the justification of interest, as interest, is not a practical question. The same observation applies to the majority of urban business men, such as small merchants and manufacturers. Their interest can be justified as not more than fair wages and profits.
