Sec. 3. The Multiplication of “Small Masters.”—Having made so much progress in our analysis, we shall approach more intelligently another important aspect of the “sweating system.” Mr. Booth and other investigators find the tap-root of the disease to consist in the multiplication of small masters. The leading industrial forces of the age, as we have seen, make for the concentration of labour in larger and larger masses, and its employment in larger and larger factories. Yet in London and in certain other large centres of population, we find certain trades which are still conducted on a small scale in little workshops or private houses, and those trades furnish a very large proportion of the worst examples of “sweating.” Here is a case of arrested development in the evolution of industry. It is even worse than that; for some trades which had been subject to the concentrating force of the factory system, have fallen into a sort of back-wash of the industrial current, and broken up again into smaller units. The increased proportion of the clothing industries conducted in private houses and small workshops is the most notorious example. This applies not only to East London, but to Liverpool, Leeds, Sheffield, and other large cities, especially where foreign labour has penetrated. For a large proportion of the sweating workshops, especially in clothing trades, are supported by foreign labour. In Liverpool during the last ten years the substitution of home-workers for workers in tailors’ shops has been marked, and in particular does this growth of home-workers apply to women.
