REPAIR, DEPRECIATION, AND DESTRUCTION OF WEALTH: RELATION TO ITS SALE AND RENT
§ I. REPAIR OF RENT-BEARING AGENTS
The necessity of repairing nearly all economic agents
1. The continued rent of indirect agents is dependent on the continual repair of certain parts necessary for their efficiency. All earthly things wear out or decay. Whenever man's hand is withheld, nature takes possession of his work, regardless of his purposes. Dust gathers on unused clothes, and moths burrow in them. Shut up a house, and windows are shattered, roofs leak, and vermin swarm. To close a factory is to hasten the time when buildings and machinery will be piled upon the rubbish heap. The most magnificent and solid works of man have crumbled under the finger of time. The earth is strewn with ruins of gigantic engineering works, aqueducts, canals, temples, and monuments, whose restoration would be no less a task than was their first building. Everywhere vigilance and repairs are the conditions of continued uses of wealth. Some works of nature, such as waterfalls, may appear to have a continued use without repair, but they bear rent only when used with other things that must be constantly mended. A certain amount of labor on the banks of the mill-stream, and certain repairs on the dam, the water-wheel, and the gates are necessary. By a fiction in business contracts the waterfall may be dealt with apart from those conditions to its use, and may be rented, as a field is, with the agreement that the tenant keep up the repairs.
The efficiency of land as mere standing-room usually does not seem to be dependent on repairs. But here again the land yields rent in connection with other rent-bearing agents (such as houses and other agents above ground), which must be repaired. Standing-room on land is not a complete indirect agent; it is but one of the conditions for carrying on an industry, and even it often requires repairs to make it usable. Ranging from these extreme cases of stableness and durability, indirect agents vary to the extremes of fragility and ephemeralness.
The fertile lands of large regions have lost their usefulness
2. Most of the qualities that contribute to make land fertile in agriculture being destructible, the constant repair of tilled land is necessary to its continued fertility. If any things could be said to be indestructible, they would be some of the works of nature. In a sense, all matter is indestructible. Man cannot annihilate it, he can simply change its condition. But in economic discussion it is the value of things that is being considered, and from this point of view everything is in some degree destructible. The effects of bad husbandry are everywhere apparent, and in many regions fertile fields have been physically and economically destroyed. In Asia, lands that once supported millions, perhaps hundreds of millions, of population are now deserts. Egypt, for a time reduced to a semi-desert condition, has only in the past century been restored to a certain extent by the use of new methods and a return to the old ones. Many of the areas that were the granaries of Rome can now hardly support a sparse, half-starving population. The lands, or at any rate, the elements that gave them value, have been destroyed.
Wearing out of some American lands
Even in young America may be seen the effect of a failure to keep land in repair. As the new rich lands of the West were opened up, the old lands in the East were allowed to wear out, and many of them were abandoned. On the new lands in turn the same methods were followed, using up the first rich store of fertility with no attempt to keep up the quality of the soil. This may have been the best policy for the time; it would not have been economical to employ Old World methods of intensive husbandry when such rich extensive areas were being opened up. But the process was one destructive of natural resources. As settlement moved westward, great forests fell in ashes, and the soil was robbed of the fertile elements which it had taken centuries for nature to store up.
Wearing out of the parts the railroad
3. The machinery and appliances used in transportation and manufacturing are all perishable in varying degrees. Take as an example the great agency for transportation, the railway. The roadbed, which is but the natural soil excavated or filled to a better grade, is the most permanent part; yet every frost weakens, every rain undermines, a portion of it. Earthquake, landslide, and flood fill up the ditches, or tear down the embankments. Constant work is needed to keep it fit and safe for use. Above this is the track, slightly less permanent, more frequently changed. The ties rot, and even the rails of steel must be at times replaced. The rolling-stock is still less durable, and the different parts vary in length of life. It is said that the wheel-tires are renewed four times, the boiler three times, and the paint seven times, before a locomotive is entirely worn out. The oil used in the wheel, which is a necessary part of the running machine, has to be applied every day.
Depreciation of manufacturing appliances
There is a great difference in the length of life of manufacturing appliances. The building is fairly durable; yet an average depreciation-rate of one and one half per cent. a year must be allowed to offset a reduction in its value of over fifty per cent, in thirty years. Machinery differs greatly in durability; well-made, substantial machinery depreciates about five per cent. yearly. The engines and boilers depreciate more rapidly than the running gear; the loose tools have to be replaced every second to fourth year; while the materials consumed in the industry must be repaired and replaced at every repetition of the process of manufacture. If a factory is to be maintained in its efficiency in accordance with the terms of the renting contract, and is to continue its renting power, everything about it must be from time to time repaired and replaced.
Neglect of repairs often has evil effects
4. Neglect or postponement of repairs must cause a falling off of the rent-earning power. The neglect of repairs may have different results in the factory. The neglect of one kind simply reduces present rental while not preventing the future restoration of the plant to its full efficiency. If certain necessary tools wear out and are not replaced, the factory as a whole will be less efficient. Each part of the entire outfit being needed in due proportion, the loss in rental will correspond not merely to the lost efficiency of the missing tools, but to the crippled efficiency of the remaining appliances. Failure to apply seed to the land causes the land as a whole to be useless for that year's crop. In other cases, neglect of repairs increases the expenses of repairs and cuts off future rental. The adages, "A stitch in time saves nine," and "An ounce of prevention is worth a pound of cure," must be acted upon in every industry. The neglect to repair a roof causes damage to an amount many times the cost of a new roof. Failure to replace a bolt costing five cents may result in the rack and ruin of a machine worth many dollars. A handful of earth on a dike may save a whole country from destruction.
But sometimes is economical
Neglect of repairs may be economical, however, when outer conditions have first reduced the demand for the agent and consequently the rental. When the line of travel changes, it does not pay to keep an old hotel up to the same state of repair as when it had a great patronage. Old factories sometimes may better be allowed to depreciate while the price of repairs is invested in more prosperous industries. In a declining neighborhood the houses fall into decay, the owners seeing that "it would not pay" to keep them up.
§ II. DEPRECIATION IN RENT-EARNING POWER OF AGENTS KEPT IN REPAIR
Repairs can not always prevent ultimate decay of agents
1. Even where repairs are thoroughly kept up and present rent is undiminished, future rents may be decreasing because of natural decay. Changes go on in the substance of things which cannot be prevented by any attention to repairs. The wood in a framework will decay, the metals crystallize. There is also an unpreventable wear of parts that cannot be replaced without replacing the whole machine. It is the aim of the modern manufacturers to make machines like the wonderful one-horse shay, every part of equal durability. The development in America of the system of "interchangable parts" has greatly simplified
