52 THE A B C OF TAXATION tion of ten, twenty, or thirty years hence are very slightly discounted to-day. Therefore, the assertion that the above programme "would visit the whole burden of the reform upon present owners ” is erroneous and confusing, especially when the burden of a three hundred dollar thirty years’ depreciation is offset by an appreciation of perhaps more than $1,500 (as is the case in Boston) which offset is rightfully a part of the economic situation. Many laws, tariff laws among others, do not pretend to insure against sporadic cases of possible injustice but the universal law remains that, with civilisation, the value of land increases. (c) The statement of the book on this point comes far short of covering the actual condition. The facts that the “selling value of land is an untaxed value” and that “the burden of a land tax cannot be made to survive a change of ownership” have indeed so increased the demand for Boston land that in value probably more than three-quarters of it is to-day in dead hands or in the hands of trustees and syndicates which cannot ­ die, all of whom refuse to loosen their grip upon this “preferred stock” except at exorbitant speculative prices which would yield income far under other lines of investment.
