The contraction of landlords’ incomes will necessarily diminish the revenue from taxation on such incomes. Let us suppose that the municipality, to maintain its revenue, puts on an additional penny in the pound. The effect will be to burn the landlord’s candle at both ends--obviously not a process that can be continued to infinity. But long before taxation fails as a source of municipal capital, the municipalities will have begun to save capital out of the product of their own industries. In the market the competition of those industries with the private concerns will be irresistible. Unsaddled with a single idle person, and having, therefore, nothing to provide for after paying their employees except extension of capital, they will be able to offer wages that no business burdened with the unproductive consumption of an idle landlord or shareholder could afford, unless it yielded a heavy rent in consequence of some marked advantage of site. But even rents, when they are town rents, are at the mercy of a municipality in the long run. The masters of the streets and the traffic can nurse one site and neglect another. The rent of a shop depends on the number of persons passing its windows per hour. A skilfully timed series of experiments in paving, a new bridge, a tramway service, a barracks, or a small-pox hospital are only a few of the circumstances of which city rents are the creatures. The power of the municipality to control these circumstances is as obvious as the impotence of competing private individuals. Again, competing private individuals are compelled to sell their produce at a price equivalent to the full cost of production at the margin of cultivation.[92] The municipality could compete against them by reducing prices to the average cost of production over the whole area of municipal cultivation. The more favorably situated private concerns could only meet this by ceasing to pay rent; the less favorably situated would succumb without remedy. It would be either stalemate or checkmate. Private property would either become barren, or it would yield to the actual cultivator of average ability no better an income than could be obtained more securely in municipal employment. To the mere proprietor it would yield nothing. Eventually the land and industry of the whole town would pass by the spontaneous action of economic forces into the hands of the municipality; and, so far, the problem of socialising industry would be solved.
