On this false basis a vast structure is erected. All prices, provided that competition is free, are made to appear as the necessary result of natural forces. They are "natural" or "normal" prices. All wages are explained, and low wages are exonerated, on what seems to be an undeniable ground of fact. They are what they are. You may wish them otherwise, but they are not. As a philanthropist, you may feel sorry that a humble laborer should work through a long day to receive two dollars, but as an economist you console yourself with the reflection that that is all he produces. You may at times, as a sentimentalist, wonder whether the vast sums drawn as interest on capital are consistent with social fairness; but if it is shown that interest is simply the "natural price" of capital representing the actual "productive power" of the capital, there is nothing further to say. You may have similar qualms over rent and the rightness and wrongness of it. The enormous "unearned increment" that accrues for the fortunate owner of land who toils not neither spins to obtain it, may seem difficult of justification. But after all, land is only one particular case of ownership under the one and the same system. The rent for which the owner can lease it, emerges simply as a consequence of the existing state of wages and prices. High rent, says the economist, does not make big prices: it merely follows as a consequence or result of them. Dear bread is not caused by the high rents paid by tenant farmers for the land: the train of cause and effect runs in the contrary direction. And the selling price of land is merely a consequence of its rental value, a simple case of capitalization of annual return into a present sum. City land, though it looks different from farm land, is seen in the light of this same analysis, to earn its rent in just the same way. The high rent of a Broadway store, says the economist, does not add a single cent to the price of the things sold in it. It is because prices are what they are that the rent is and can be paid. Hence on examination the same canon of social justice that covers and explains prices, wages, and interest applies with perfect propriety to rent.
