A. D. Smith, The Development of Rates of Postage…
“ The Post Office, therefore, is at present one of the best sources from which this country derives its revenue. But a postage much exceeding what would be paid for the same service in a system of freedom is not a desirable tax. Its chief weight falls on letters of business, and increases the expense of mercantile relations between distant places. It is like an attempt to raise a large revenue by heavy tolls: it obstructs all operations by which goods are conveyed from place to place, and discourages the production of commodities in one place for consumption in another ”
