Quotes

 * Bad ventilation, deep excavation, defective supports, etc., etc., annually bring death to thousands of miners, but this system of operation saves expenses, therefore augments the gains, and gives the mine owners no occasion to be sorry. Neither does the factory-pasha care how many of "his" laborers are torn and rent apart by machinery, poisoned by chemicals, or slowly suffocated by dirt and dust. Profit is the main thing.
 * Johann Most, The Beast of Property (1884)
