It is important that the value of any commodity and the duties laid on it should be so proportioned that the avarice of individuals may not be too strongly tempted to fraud by the greatness of the possible profit. To make smuggling difficult, those commodities should be singled out which are hardest to conceal. All duties should be rather paid by the consumer of the commodity taxed than by him who sells it: as the quantity of duty he would be obliged to pay would lay him open to greater temptations, and afford him more opportunities for fraud. This is the constant custom in China, a country where the taxes are greater and yet better paid than in any other part of the world. The merchant himself there pays no duty; the buyer alone, without murmuring or sedition, meets the whole charge; for as the necessaries of life, such as rice and corn, are absolutely exempt from taxation, the common people is not oppressed, and the duty falls only on those who are well-to-do. Precautions against smuggling ought not to be dictated so much by the fear of it occurring, as by the attention which the government should pay to securing individuals from being seduced by illegitimate profits, which first make them bad citizens, and afterwards soon turn them into dishonest men. Heavy taxes should be laid on servants in livery, on equipages, rich furniture, fine clothes, on spacious courts and gardens, on public entertainments of all kinds, on useless professions, such as dancers, singers, players, and in a word, on all that multiplicity of objects of luxury, amusement and idleness, which strike the eyes of all, and can the less be hidden, as their whole purpose is to be seen, without which they would be useless. We need be under no apprehension of the produce of these taxes being arbitrary, because they are laid on things not absolutely necessary. They must know but little of mankind who imagine that, after they have been once seduced by luxury, they can ever renounce it: they would a hundred times sooner renounce common necessaries, and had much rather die of hunger than of shame. The increase in their expense is only an additional reason for supporting them, when the vanity of appearing wealthy reaps its profit from the price of the thing and the charge of the tax. As long as there are rich people in the world, they will be desirous of distinguishing themselves from the poor, nor can the State devise a revenue less burdensome or more certain than what arises from this distinction.
