"If the imposition of the tax does not diminish the demand, it will leave the trade exactly as it was before. We shall import as much, and export as much; the whole of the tax will be paid out of our own pockets.

It may, therefore, be laid down as a principle, that a tax on imported commodities, when it really operates as a tax, and not as a prohibition either total or partial, almost always falls in part upon the foreigners who consume our goods; and that this is a mode in which a nation may appropriate to itself, at the expense of foreigners, a larger share than would otherwise belong to it of the increase in the general productiveness of the labour and capital of the world, which results from the interchange of commodities among nations."
Those are, therefore, in the right who maintain that taxes on imports are partly paid by foreigners; but they are mistaken when they say, that it is by the foreign producer.
