Lands, for the purposes of pleasure and magnificence, parks, gardens, public walks, etc. possessions which are everywhere considered as causes of expense, not as sources of revenue, seem to be the only lands which, in a great and civilized monarchy, ought to belong to the crown.
Public stock and public lands, therefore, the two sources of revenue which may peculiarly belong to the sovereign or commonwealth, being both improper and insufficient funds for defraying the necessary expense of any great and civilized state; it remains that this expense must, the greater part of it, be defrayed by taxes of one kind or another; the people contributing a part of their own private revenue in order to make up a public revenue to the sovereign or commonwealth.
II
Of Taxes
The private revenue of individuals, it has been shown in the first book of this Inquiry, arises ultimately from three different sources; Rent, Profit, and Wages. Every tax must finally be paid from some one or other of those three different sorts of revenue, or from all of them indifferently. I shall endeavour to give the best account I can, first, of those taxes which, it is intended, should fall upon rent; secondly, of those which, it is intended, should fall upon profit; thirdly, of those which, it is intended, should fall upon wages; and, fourthly, of those which, it is intended, should fall indifferently upon all those three different sources of private revenue. The particular consideration of each of these four different sorts of taxes will divide the second part of the present chapter into four articles, three of which will require several other subdivisions. Many of those taxes, it will appear from the following review, are not finally paid from the fund, or source of revenue, upon which it was intended they should fall.
