There is a prevailing maxim, among some reasoners, that every new tax creates a new ability in the subject to bear it, and that each encrease of public burdens encreases proportionably the industry of the people. This maxim is of such a nature as is most likely to be abused; and is so much the more dangerous, as its truth cannot be altogether denied: but it must be owned, when kept within certain bounds, to have some foundation in reason and experience.

When a tax is laid upon commodities, which are consumed by the common people, the necessary consequence may seem to be, either that the poor must retrench something from their way of living, or raise their wages, so as to make the burden of the tax fall entirely upon the rich. But there is a third consequence, which often follows upon taxes, namely, that the poor encrease their industry, perform more work, and live as well as before, without demanding more for their labour. Where taxes are moderate, are laid on gradually, and affect not the necessaries of life, this consequence naturally follows; and it is certain, that such difficulties often serve to excite the industry of a people, and render them more opulent and laborious, than others, who enjoy the greatest advantages. For we may observe, as a parallel instance, that the most commercial nations have not always possessed the greatest extent of fertile land; but, on the contrary, that they have laboured under many natural disadvantages. TYRE, ATHENS, CARTHAGE, RHODES, GENOA, VENICE, HOLLAND, are strong examples to this purpose. And in all history, we find only three instances of large and fertile countries, which have possessed much trade; the NETHERLANDS. ENGLAND, and FRANCE. The two former seem to have been allured by the advantages of their maritime situation, and the necessity they lay under of frequenting foreign ports, in order to procure what their own climate refused them. And as to FRANCE, trade has come late into that kingdom, and seems to have been the effect of reflection and observation in an ingenious and enterprizing people, who remarked the riches acquired by such of the neighbouring nations as cultivated navigation and commerce.

The places mentioned by CICERO, as possessed of the greatest commerce in his time, are ALEXANDRIA, COLCHUS, TYRE, SIDON, ANDROS, CYPRUS, PAMPHYLIA, LYCIA, RHODES, CHIOS, BYZANTIUM, LESBOS, SMYRNA, MILETUM, COOS. All these, except ALEXANDRIA, were either small islands, or narrow territories. And that city owed its trade entirely to the happiness of its situation.

Since therefore some natural necessities or disadvantages may be thought favourable to industry, why may not artificial burdens have the same effect? Sir WILLIAM TEMPLE, we may observe, ascribes the industry of the DUTCH entirely to necessity, proceeding from their natural disadvantages; and illustrates his doctrine by a striking comparison with IRELAND; "where," says he, "by the largeness and plenty of the soil, and scarcity of people, all things necessary to life are so cheap, that an industrious man, by two days labour, may gain enough to feed him the rest of the week. Which I take to be a very plain ground of the laziness attributed to the people. For men naturally prefer ease before labour, and will not take pains if they can live idle; though when, by necessity, they have been inured to it, they cannot leave it, being grown a custom necessary to their health, and to their very entertainment. Nor perhaps is the change harder, from constant ease to labour, than from constant labour to ease."After which the author proceeds to confirm his doctrine, by enumerating, as above, the places where trade has most flourished, in ancient and modern times; and which are commonly observed to be such narrow confined territories, as beget a necessity for industry.

The best taxes are such as are levied upon consumptions, especially those of luxury; because such taxes are least felt by the people. They seem, in some measure, voluntary; since a man may chuse how far he will use the commodity which is taxed: They are paid gradually and insensibly: They naturally produce sobriety and frugality, if judiciously imposed: And being confounded with the natural price of the commodity, they are scarcely perceived by the consumers. Their only disadvantage is, that they are expensive in the levying.

Taxes upon possessions are levied without expence; but have every other disadvantage. Most states, however, are obliged to have recourse to them, in order to supply the deficiencies of the other.
