The Wealth of Nations_ Books 4-5 - Adam Smith [269]
The tythe, as it is frequently a very unequal tax upon the rent, so it is always a great discouragement both to the improvements of the landlord and to the cultivation of the farmer. The one cannot venture to make the most important, which are generally the most expensive improvements, nor the other to raise the most valuable, which are generally too the most expensive crops, when the church, which lays out no part of the expense, is to share so very largely in the profit. The cultivation of madder was for a long time confined by the tythe to the United Provinces, which, being Presbyterian countries, and upon that account exempted from this destructive tax, enjoyed a sort of monopoly of that useful dyeing drug against the rest of Europe. The late attempts to introduce the culture of this plant into England have been made only in consequence of the statute which enacted that five shillings an acre should be received in lieu of all manner of tythe upon madder.
As through the greater part of Europe the church, so in many different countries of Asia the state, is principally supported by a land-tax, proportioned, not to the rent, but to the produce of the land. In China, the principal revenue of the sovereign consists in a tenth part of the produce of all the lands of the empire. This tenth part, however, is estimated so very moderately that, in many provinces, it is said not to exceed a thirtieth part of the ordinary produce. The land-tax or land-rent which used to be paid to the Mahometan government of Bengal, before that country fell into the hands of the English East India Company, is said to have amounted to about a fifth part of the produce. The land-tax of ancient Egypt is said likewise to have amounted to a fifth part.
In Asia, this sort of land-tax is said to interest the sovereign in the improvement and cultivation of land. The sovereigns of China, those of Bengal while under the Mahometan government, and those of ancient Egypt, are said accordingly to have been extremely attentive to the making and maintaining of good roads and navigable canals, in order to increase, as much as possible, both the quantity and value of every part of the produce of the land, by procuring to every part of it the most extensive market which their own dominions could afford. The tythe of the church is divided into such small portions that no one of its proprietors can have any interest of this kind. The parson of a parish could never find his account in making a road or canal to a distant part of the country, in order to extend the market for the produce of his own particular parish. Such taxes when destined for the maintenance of the state, have some advantages which may serve in some measure to balance their inconveniency. When destined for the maintenance of the church, they are attended with nothing but inconveniency.
Taxes upon the produce of land may be levied either in kind, or, according to a certain valuation, in money.
The parson of a parish, or a gentleman of small fortune who lives upon his estate, may sometimes, perhaps, find some advantage in receiving, the one his tythe, and the other his rent, in kind. The quantity to be collected, and the district within which it is to be collected, are so small that they both can oversee, with their own eyes, the collection and disposal of every part of what is due to them. A gentleman of great fortune, who lived in the capital, would be in danger of suffering much by the neglect, and more by the fraud of his factors and agents, if the rents of an estate in a distant province were to be paid to him in this manner. The loss of the sovereign from the abuse and depredation of his tax-gatherers would necessarily be much greater. The servants of the most careless private person are, perhaps, more under the eye of their master than those of the most careful prince; and a public revenue which was paid in kind would suffer so much from the mismanagement of the collectors that a very small part of what was levied upon the people would ever arrive at the treasury of the prince.
