The following argument of M. Say is founded on the same views as Mr. Buchanan's:
"The quantity of wine or corn which a piece of land will produce, will remain nearly the same, whatever may be the tax with which it is charged. The tax may take away a half, or even three-fourths of its net produce, or of its rent if you please, yet the land would nevertheless be cultivated for the half or the quarter not absorbed by the tax. The rent, that is to say the landlord's share, would merely be somewhat lower. The reason of this will be perceived, if we consider, that in the case supposed, the quantity of produce obtained from the land, and sent to market, will remain nevertheless the same. On the other hand the motives on which the demand for the produce is founded continue also the same.
"Now, if the quantity of produce supplied, and the quantity demanded, necessarily continue the same, notwithstanding the establishment or the increase of the tax, the price of that produce will not vary; and if the price do not vary, the consumer will not pay the smallest portion of this tax.
"Will it be said that the farmer, he who furnishes labour and capital, will, jointly with the landlord, bear the burden of this tax? certainly not; because the circumstance or the tax has not diminished the number of farms to be let, nor increased the number of farmers. Since in this instance also the supply and demand remain the same, the rent of farms must also remain the same. The example of the manufacturer of salt, who can only make the consumers pay a portion of the tax, and that of the landlord who cannot reimburse himself in the smallest degree, prove the error of those who maintain, in opposition to the economists, that all taxes fall ultimately on the consumer."—Vol. ii. p. 338.
