amount, we should, I think, have reached the prudent limits of direct taxation, save in a national emergency so urgent as to justify the government in disregarding the amount of inequality and unfairness which may ultimately be found inseparable from an income tax. The remainder of the revenue would have to be provided by taxes on consumption, and the question is, which of these are the least objectionable.
§ 2.There are some forms of indirect taxation which must be peremptorily excluded. Taxes on commodities, for revenue purposes, must not operate as protecting duties, but must be levied impartially on every mode in which the articles can be obtained, whether produced in the country itself, or imported. An exclusion must also be put upon all taxes on the necessaries of life, or on the materials or instruments employed in producing those necessaries. Such taxes are always liable to encroach on what should be left untaxed, the incomes barely sufficient for healthful existence; and on the most favourable supposition, namely, that wages rise to compensate the labourers for the tax, it operates as a peculiar tax on profits, which is at once unjust, and detrimental to national wealth.[1] What remain are taxes on luxuries. And these have some properties which strongly recommend them. In the first place, they can never, by any possibility, touch those whose whole income is expended on necessaries; while they do reach those by whom what is required for necessaries, is expended on indulgences. In the next place, they operate in some cases as an useful, and the only useful, kind
- ↑ Some argue that the materials and instruments of all production should be exempt from taxation; but these, when they do not enter into the production of necessaries, seem as proper subjects of taxation as the finished article. It is chiefly with reference to foreign trade, that such taxes have been considered injurious. Internationally speaking, they may be looked upon as export duties, and, unless in cases in which an export duty is advisable, they should be accompanied with an equivalent drawback on exportation. But there is no sufficient reason against taxing the materials and instruments used in the production of anything which is itself a fit object of taxation.
