226. The question then remains, whether the full development of those rights, as including that of unlimited accumulation of wealth by the individual and of complete freedom of bequest on his part, necessarily carries with it the existence of a proletariate, nominal owners of their powers of labour, but in fact obliged to sell these on such terms that they are owners of nothing beyond what is necessary from day to day for the support of life, and may at any time lose even that, so that, as regards the moral functions of property, they may be held to be not proprietors at all; or whether the existence of such a class is due to causes only accidentally connected with the development of rights of individual property. We must bear in mind (1) that the increased wealth of one man does not naturally mean the diminished wealth of another. We must not think of wealth as a given stock of commodities of which a larger share cannot fall to one without taking from the share that falls to another. The wealth of the world is constantly increasing in proportion as the constant production of new wealth by labour exceeds the constant consumption of what is already produced, There is no natural limit to its increase except such as arises from the fact that the supply of the food necessary to sustain labour becomes more difficult as more comes to be required owing to the increase in the number of labourers, and from the possible ultimate exhaustion of the raw materials of labour in the world. Therefore in the accumulation of wealth, so far as it arises from the saving by anyone of the products of his labour, from his bequest of this capital to another who farther adds to it by saving some of the profit which the capital yields, as employed in the payment for labour or in trade either by the capitalist himself or someone to whom he lends it, and from the continuation of this process through generations, there is nothing which tends to lessen for anyone else the possibilities of ownership. On the contrary, supposing trade and labour to be free, wealth must be constantly distributed throughout the process in the shape of wages to labourers and of profits to those who mediate in the business of exchange.
