But this is not the only objection to taxes on the transference of property; they prevent the national capital from being distributed in the way most beneficial to the community. For the general prosperity, there cannot be too much facility given to the conveyance and exchange of all kinds of property, as it is by such means that capital of every species is likely to find its way into the hands of those who will best employ it in increasing the productions of the country. "Why," asks M. Say, "does an individual wish to sell his land? it is because he has another employment in view in which his funds will be more productive. Why does another wish to purchase this same land? it is to employ a capital which brings him in too little, which was unemployed, or the use of which he thinks susceptible of improvement. This exchange will increase the general income, since it increases the income of these parties. But if the charges are so exorbitant as to prevent the exchange, they are an obstacle to this increase of the general income." Those taxes however are easily collected; and this by many may be thought to afford some compensation for their injurious effects.
Having in a former part of this work established, I hope satisfactorily, the principle, that the price of corn is regulated by the cost of its production on that land exclusively, or rather with that capital exclusively, which pays no rent, it will follow that whatever may increase the cost of production will increase the price; whatever may reduce it, will lower the price. The necessity of cultivating poorer land, or of obtaining a less return with a given additional capital on land already in cultivation, will inevitably raise the exchangeable value of raw produce. The discovery of machinery, which will enable the cultivator to obtain his corn at a less cost of production, will necessarily lower its exchangeable value. Any tax which may be imposed on the cultivator, whether in the shape of land-tax, tithes, or a tax on the produce when obtained, will increase the cost of production, and will therefore raise the price of raw produce.
If the price of raw produce did not rise so as to compensate the cultivator for the tax, he would naturally quit a trade where his profits were reduced below the general level of profits: this would occasion a diminution of supply, until the unabated demand should have produced such a rise in the price of raw produce, as to make the cultivation of it equally profitable with the investment of capital in any other trade.
