country considered separately, it may, at least on the particular occasion, be an inconvenience: but taking into account that the country which is now the giver, will in some future season be the receiver, and the one that is benefited by the freedom, I cannot but think that even to the apprehension of food rioters it might be made apparent, that in such cases they should do to others what they would wish done to themselves.
In countries in which the Protection theory is declining, but not yet given up, such as the United States, a doctrine has come into notice which is a sort of compromise between free trade and restriction, namely, that protection for protection's sake is improper, but that there is nothing objectionable in having as much protection as may incidentally result from a tariff framed solely for revenue. Even in England, regret is sometimes expressed that a "moderate fixed duty" was not preserved on corn, on account of the revenue it would yield. Independently, however, of the general impolicy of taxes on the necessaries of life, this doctrine overlooks the fact, that revenue is received only on the quantity imported, but that the tax is paid on the entire quantity consumed. To make the public pay much that the treasury may receive a little, is not an eligible mode of obtaining a revenue. In the case of manufactured articles the doctrine involves a palpable inconsistency. The object of the duty as a means of revenue, is inconsistent with its affording, even incidentally, any protection. It can only operate as protection in so far as it prevents importation; and to whatever degree it prevents importation, it affords no revenue.
The only case in which, on mere principles of political economy, protecting duties can be defensible, is when they are imposed temporarily (especially in a young and rising nation) in hopes of naturalizing a foreign industry, in itself perfectly suitable to the circumstances of the country. The superiority of one country over another in a branch of production, often arises only from having begun it sooner.
