as a barrier against political or local pressure in the direction of uncommercial concessions, whether of new lines or of extended facilities or reduced rates on the old lines; but--and here is the fundamental difference between the new system and the old--whereas under the old system the final appeal was to a body of shareholders with no interest beyond their own dividend, the majority shareholder is now the Government of Mexico, with every inducement to regard the interests, both present and prospective, of the country as a whole. IRREFRAGABLE THEORY OF PUBLIC OWNERSHIP. Public ownership of railroads is in theory irrefragable. Railroads are a public service; it is right that they should be operated by public servants in the public interest. Unfortunately, especially in democratically organized communities, the facts have not infrequently refused to fit the theories, and the public servants have allowed, or been constrained to allow, the railroads to be run, not in the permanent interest of the community as a whole, but in the temporary interest of that portion of the community which at the moment could exert the most strenuous pressure. The Mexican system, if it succeeds in establishing itself permanently--for as yet it is only on its trial--may perhaps have avoided both Scylla and Charybdis. Faced with a powerful but local and temporary demand, the government may be able to reply that this is a matter to be dealt with on commercial lines by the board of directors. If, on the other hand, permanent national interests are involved, the government can exercise its reserve power as a shareholder, can vote the directors out of office, and so prevent the continuance of a policy which would in its judgment be prejudicial to those interests, however much it might be to the advantage of the railroad as a mere commercial concern. STATE CONTROL OR OWNERSHIP.
