These may be summed up under three heads: making land easier to acquire; cheapening the products and rent of land; and reducing the burdens of taxation borne by the poorer and middle classes. An increase in the tax on land would reduce its value and price, or at least cause the price to be lower than it would have been in the absence of the tax. This does not mean that land would be more profitable to the purchaser, since he is enabled to buy it at a lower price only because it yields him less net revenue, or because it is less likely to increase in value. The value of land is always determined by its revenue-producing power, and by its probabilities of price-appreciation. Consequently, what the purchasers would gain by the lower price resulting from the new tax, they would lose when they came to pay the tax itself, and when they found the chances of value increases diminished. If a piece of land which brings a return of five dollars a year costs one hundred dollars before the new tax of one per cent. is imposed, and can be bought for eighty dollars afterward, the net interest on the purchase price has not changed. It is still five per cent. Hence the only advantage to the prospective purchaser of land in getting it cheaper consists in the fact that he can obtain it with a smaller outlay of capital. For persons in moderate circumstances this is a very important consideration. In the second place, higher taxes would cause many existing owners either to improve their land, in order to have the means of meeting the added fiscal charges, or to sell it to persons who would be willing to make improvements. And the desire to erect buildings and other forms of improvements would be reinforced by the reduction or abolition of taxes on those kinds of personal property which consist of building materials. An increase in the rapidity of improvements on land would mean an increase in the rate at which land was brought into use, and therefore an unusual increase in the volume of products. This virtual increase in the supply of land, and actual increase in the supply of products, would cause a fall in three kinds of prices: the price of products, the rent of land, and the price of land. The last named reduction would be distinct from the reduction of land value caused in the first instance by the imposition of the tax.
