income. This involves a burden that is ruinous in some cases, both to borrowers and to lenders, and that tempts in all cases to the evasion of the tax. Take, for example, a house assessed at $10,000 which is owned free of debt and which has a rental value of $600. At the rate of 1.5 per cent the tax paid would be $150. Now if the owner borrows $8000 he is still taxable $150 on the full value of the house, and the lender nearly everywhere is taxable $120 on the amount of his mortgage. The total tax payable out of the one source of income, the house, is then $270. The same analysis will show that any credit is but a contractual claim upon some other source of income which is, or should have been, already taxed. If one person owns all the capital-value invested in a specific piece of wealth, no attempt is made to tax both the capital and the wealth; but if it happens that two or more persons share the capital-value invested in the same wealth, the attempt is made to tax as a unit the full value of the wealth and, in addition, some part of the capital also. It is, however, easy in most cases to conceal this "intangible property" from the assessor's eyes, and a comparatively small amount of it is ever taxed. This means inequality and hardship in the operation of the tax and, as a result, unceasing temptation to perjury by the taxpayer and to favoritism and graft by public officials. § 4. #Various temporizing policies.# The general property tax in practice is unjust and demoralizing. What, then, shall be done about it? Various policies have been followed. One has been to declare that the law would be good if it could be enforced, but that as in practice it cannot be, the best thing is to go on as before, catching a few "tax dodgers," and letting the rest go. Another policy is to hire "tax ferrets," paying them large commissions to discover cases where intangible property of this sort has been concealed from the assessors. This method, no matter how stringently applied, has never reached more than a small proportion of the cases, and becomes a potent agency of political favoritism and corruption.
