The character of the housing and working places could well be left to individuals in early times. If the individual chose to live and work in unsuitable places and under unsanitary conditions, it was usually his own fault and he bore the consequences. When the unsanitary conditions about each family are visited upon its neighbors, society must deal with them. Engineering, sanitary science, and medicine must be directed against the evils; factory and tenement-house legislation must seek to make possible a decent life in the cities, the factories, and the homes. Indeed, in many places the development in these and other directions has enabled the mass of the workers to enjoy blessings impossible to the most favored in the past. § II. SOCIAL CONDITIONS FAVORING EFFICIENCY [Sidenote: Government to insure the reward to labor] 1. _The first social condition for the workers' efficiency is political security._ For the same reason that this condition is favorable to the growth of capital, it is essential if men are to labor in the present and for the future. As the framers of the Constitution expressed it, the function of government is to insure domestic tranquillity, provide for the common defense, and insure the blessings of liberty to the citizen. Directness and certainty of reward are more essential than mere size of reward in insuring action and effort. There must be a close relation between work and the fruits of work. Political insecurity weakens this relation and makes the reward dependent on chance. [Sidenote: Common honesty as a condition to efficient labor] 2. _The prevalence of standards of honesty in private and public business is a condition to high efficiency._ Corruption in government has the same effect as political insecurity; in fact, it is but another form of it. We are accustomed to the thought that in an Asiatic despotism a worker beginning a task is uncertain whether he will reap the reward, as public officials may at any moment seize upon the fruits of his labor. But in our own country similar evils are not entirely lacking. Assessments often are unfair, and justice sometimes is bought. Men in high executive positions are able to make or mar the fortunes of their followers. Sometimes a legislator from a country town goes to the state capital poor and returns rich. Such things becoming generally known tend to break down the motives to industry. They breed the notion that wealth is more dependent on chance or jobbery than on efficient service. Dishonesty in private business means the use of energy not to produce wealth, not to add to the sum for all to enjoy, but to get it from some one else. Public corruption and commercial dishonesty alike entail on the industrious not only the immediate loss, but the far greater cost of weakened character, relaxed energy, and decreased efficiency of labor.
