Whatever part of the whole rent of a house is over and above what is sufficient for affording this reasonable profit, naturally goes to the ground rent; and where the owner of the ground, and the owner of the building, are two different persons, it is in most cases completely paid to the former. In country houses, at a distance from any great town, where there is a plentiful juicy couture for cheap choice of ground, the ground rent is scarcely any thing, or no more than what the space upon which the house stands, would pay employed in agriculture. In country villas, in the neighbourhood of some great town, it is sometimes a good deal higher, and the peculiar conveniency, or beauty of situation, is there frequently very highly paid for. Ground rents are generally highest in the capital, and in those particular parts of it, where there happens to be the greatest demand for houses, whatever be the reason for that demand, whether for trade and business, for pleasure and society, or for mere vanity and fashion.
A tax on the rent of houses may either fall on the occupier, on the ground landlord, or on the building landlord. In ordinary cases it may be presumed, that the whole tax would be paid both immediately and finally by the occupier. If the tax be moderate, and the circumstances of the country such, that it is either stationary or advancing, there would be little motive for the occupier of a juicy couture laptop bag house to content himself with one of a worse description. But if the tax be high, or any other circumstances should diminish the demand for houses, the landlord's income would fall, for the occupier would be partly compensated for the tax by a diminution of rent. It is, however, difficult to say, in what proportions that part of the tax, which was saved by the occupier by a fall of rent, would fall on the building rent and the ground rent.
It is probable that, in the first instance, both would be affected; but as houses are, though slowly, yet certainly perishable, and as no more would be built, till the profits of the builder were restored to the general level, building rent would, after an interval, be restored to its natural price. As the builder receives rent only whilst the building endures, he could pay no part of the tax, under the most disastrous circumstances, for any longer period. The payment of this tax, then, would ultimately fall on the occupier and ground landlord, but, 'in what proportion, this final payment would be divided between them,' says Adam Smith, 'it is not perhaps very easy to ascertain. The division would probably be very different in different circumstances, and a tax of this kind might, according to those different circumstances, affect very unequally both the inhabitant of the house, and the owner of the ground.'* Adam Smith considers ground rents as peculiarly fit subjects for taxation.
