burthen cannot be apportioned with any tolerable approach to fairness upon those whose incomes are derived from business or professions; and this is in fact admitted by most of the advocates of direct taxation, who, I am afraid, generally get over the difficulty by leaving those classes untaxed, and confining their projected income tax to "realized property," in which form it certainly has the merit of being a very easy form of plunder. But enough has been said in condemnation of this expedient. We have seen, however, that a house tax is a form of direct taxation not liable to the same objections as an income tax, and indeed liable to as few objections of any kind as perhaps any of our indirect taxes. But it would be impossible to raise by a house tax alone, the greatest part of the revenue of Great Britain, without producing a very objectionable over-crowding of the population, through the strong motive which all persons would have to avoid the tax by restricting their house accommodation. Besides, even a house tax has inequalities, and consequent injustices; no tax is exempt from them, and it is neither just nor politic to make all the inequalities fall in the same places, by calling upon one tax to defray the whole or the chief part of the public expenditure. So much of the local taxation, in this country, being already in the form of a house tax, it is probable that ten millions a year would be fully as much as could beneficially be levied, through this medium, for general purposes.
A certain amount of revenue may, as we have seen, be obtained without injustice by a peculiar tax on rent. Besides the present land-tax, and an equivalent for the revenue now derived from stamp duties on the conveyance of land, some further taxation might, I have contended, at some future period be imposed, to enable the state to participate in the progressive increase of the incomes of landlords from natural causes. Legacies and inheritances, we have also seen, ought to be subjected to taxation sufficient to yield a considerable revenue. With these taxes, and a house tax of suitable
