You ask some practical questions which it may be well to answer: "How will you prevent the Standard Oil Company forcing weaker concerns to the wall by the simple expedient of selling below cost of production?" The Standard Oil trust is maintained (1) by monopoly of oil lands; (2) by monopoly of pipe lines; (3) by collusion with railroads. The Single Tax and its corollaries would absolutely destroy each of these advantages; (1) by throwing unused oil lands open to all on equal terms; (2) by government ownership or complete control of pipe lines to all distributing points, such lines being open for use to all oil producers on equal terms; (3) by exactly analogous treatment of railroads. With the three-fold monopoly of oil lands, pipe line, and railroad abolished, the Standard Oil trust would find no wall against which to crush weaker concerns. As to the trust, we hope that the abolishment of the thieves' compact, i.e. the protective tariff, will make the trusts sick unto death. Absolute free trade, a necessary concomitant of the Single Tax, will leave 99 per cent. of the trusts stranded. If any survive it will not be the fault of the Single Tax. Be it remembered that the evils which the Single Tax is guaranteed to cure are, primarily, land monopoly, and, secondarily, all the other monopolies based upon it; as those of the coal, iron and lumber trust, the Standard Oil trust, etc. "With coal fields leased to the operators by Uncle Sam, how would you prevent Hanna organizing a pool, limiting production, raising prices and reducing wages?" Coal fields are included in the economic term, land. When unused land is free for occupancy, unused coal fields will also be free. If Mark sought to limit production by shutting down his mines, one of two things would happen. Either somebody else would start in to mine coal, or Mark's tax would be raised till the wisdom of either letting go or resuming would dawn on his fat wits. Unless he owned or controlled the coal fields he could not limit production, raise prices, or cut down wages. "How will you prevent the Standard Oil company forcing weaker concerns to the wall by the simple expedient of selling below cost of production?" We wouldn't prevent them. But if they afterwards tried to recoup their losses by raising prices as they do now, we might get after them with a tax commensurate with their asinine generosity, and keep after them till other concerns got well on their feet. If they became too refractory, what's to prevent the government from taking hold itself and working the oil wells for the benefit of the whole people? Remember the government is theoretically the people's servant, and it could be actually so if the people only had a little intelligence and moral courage.
