Rh In these several modes, taxes on commodities often cost to the consumer, through the increased price of the article, much more than they bring into the treasury of the state. There is still another consideration. The higher price necessitated by the tax, almost always checks the demand for the commodity; and since there are many improvements in production which, to make them practicable, require a certain extent of demand, such improvements are obstructed, and many of them prevented altogether. It is a well-known fact, that the branches of production in which fewest improvements are made, are those with which the revenue officer interferes; and that nothing, in general, gives a greater impulse to improvements in the production of a commodity, than taking off a tax which narrowed the market for it.

§ 3. Such are the effects of taxes on commodities, considered generally; but as there are some commodities (those composing the necessaries of the labourer) of which the values have an influence on the distribution of wealth among different classes of the community, it is requisite to trace the effects of taxes on those particular articles somewhat farther. If a tax be laid, say on corn, and the price rises in proportion to the tax, the rise of price may operate in two ways. First: it may lower the condition of the labouring classes; temporarily indeed it can scarcely fail to do so. If it diminishes their consumption of the produce of the earth, or makes them resort to a food which the soil produces more abundantly, and therefore more cheaply, it to that extent contributes to throw back agriculture upon more fertile lands or less costly processes, and to lower the value and price of corn; which therefore ultimately settles at a price, increased not by the whole amount of the tax, but by only a part of its amount. Secondly, however, it may happen that the dearness of the taxed food does not lower the habitual standard of the labourer's requirements, but that wages, on the contrary, through
