There are included in the minimum requirements such provisions as will make possible a house in which any person can live comfortably and decently. A house built under these conditions will not contain many of the features which, while not absolutely necessary, are desired by many workmen's families.
If the term "Industrial Housing" applied only to the lowest-paid unskilled workers, it would be unnecessary to consider any but essential features; however, a large percentage of wage earners are skilled workmen, who, imbued with higher standards of living, not only desire but demand additional features in the house. They are able and willing to pay for such conveniences. It, therefore, seems necessary to arrive at some classification of houses suitable to the corresponding grades of workmen which exist in the personnel of industry.
Many persons have deemed two classifications all that are necessary - one for unskilled workers, and one for skilled workers. This differentiation, however, is considered to be too abrupt and not furnishing sufficient gradation, by men intimately acquainted with the wage earner and his family life. The native unskilled worker must often be provided with a better house than the rank and file of unskilled wage earners, and yet he cannot pay for the houses provided for higher paid skilled workers. On the other hand, if he does not have children, he probably is in a better position to afford these accommodations than the skilled worker with a very large family, who certainly will never be satisfied to drop down to the grade of house provided for unskilled laborers.
