“Honor sinks where commerce long prevails.”

Report on Manufactures (1791)
Context: If the system of perfect liberty to industry and commerce were the prevailing system of nations, the arguments which dissuade a country in the predicament of the United States, from the zealous pursuits of manufactures would doubtless have great force. (...) But the system which has been mentioned, is far from characterising the general policy of Nations. The prevalent one has been regulated by an opposite spirit. The consequence of it is, that the United States are to a certain extent in the situation of a country precluded from foreign Commerce. They can indeed, without difficulty obtain from abroad the manufactured supplies, of which they are in want; but they experience numerous and very injurious impediments to the emission and vent of their own commodities. (...) In such a position of things, the United States cannot exchange with Europe on equal terms, and the want of reciprocity would render them the victim of a system, which should induce them to confine their views to Agriculture and refrain from Manufactures. A constant and increasing necessity, on their part, for the commodities of Europe, and only a partial and occasional demand for their own, in return, could not but expose them to a state of impoverishment, compared with the opulence to which their political and natural advantages authorise them to aspire.
