74 THE A B C OF TAXATION this instance for the landowners. This may be an extreme illustration, but it goes to show the vicious ness of the present system, and points unerringly to the sufficiency of ground rents for all purposes of taxation. Few persons now call in question the right of the owner of any Washington Street lot to tear down his building and hold his lot vacant. If one owner may do this all owners may do the same. Must there not be some fatal weakness in an apportionment between the rights of individuals and the rights of the people that would make possible such an impolitic condition? But the fact that modern buildings would be worth $50 to $75 per square foot instead of $13.50, the value of present buildings, is proof that most of this land, though not held entirely vacant, is held practically three-quarters to nine-tenths vacant, or, in other words, put only to one-quarter or one-tenth of its legitimate and most economical use. A public economy that turns a landowner from a public friend into a public enemy, whether he will or no, cannot be wise. If Boston should take the $4,383 received for taxes from the marble Sears Building on Washington Street, and the $7,465 from the Ames Building, and spend these amounts in the improvement and repair of the worthless buildings of Washington Street, the owners of the Sears and Ames Buildings would complain, and very justly. Exactly what the City of Boston does is this: It spends these same taxes in the “improve ment and repair” of the land value that is under these and similar buildings. But is this really less unjust? This is one more way of looking at the unequal incidence of a tax on buildings.
