In the last analysis it is evident that the monopoly of entrance to a city is really a monopoly in land, or, we might more properly say, in space. We are fortunate in this country in having millions of acres of land still awaiting cultivation; and while it is not intended here to defend the policy of _giving away_ the estate of the public which our government has pursued, there is no danger for a long time to come that an actual monopoly will exist in agricultural lands. The price of land used for business purposes in a city, however, depends almost wholly upon its location. The price at which a single block of land near Wall Street, in New York City, was recently sold was so great that, at the same price, the value of a square mile would be equal to half the whole estimated wealth of every sort in the United States. Now the question must occur to every thinking man, by what right does the owner of this property receive this enormous wealth? To make the case of those who advocate the public control of the gifts of Nature more clear, let us consider a special case. Suppose a man in an Eastern city chanced to come into possession two-score years ago of a tract of land in what is now Kansas City. We may suppose that he got it by inheritance, or through some chance, and that, except to pay the taxes upon it, he has never given farther attention to it. During all the years of the city's rapid growth he pays no attention to his land and takes no part in furthering the growth of the city. At last, at the height of the real-estate boom, he sells the land, and, whereas it cost him in the first instance a merely nominal sum, perhaps $100, he sells it now for $100,000. This value it has, not because of itself, as is the case with farming lands, but because of its situation in reference to the community around it. In other words, practically the whole value of this land has been given it by the people who have come and built this city around it. It is their labor that has given this property its value, and, in equity, the value should be theirs. A more detailed statement of the arguments for the public control of land incomes cannot be given here. What we are concerned with here is the extent to which land is subject to a monopoly. It appears too evident to require further discussion that, as a general rule, agricultural lands in every section of the country are competing to a greater or less extent with lands in every other section, and that the lands used for business purposes in the cities compete likewise, each city with others neighboring and of similar size, while lands in the same city similarly situated compete with each other.
