"So long as we have wage slavery," answered Schliemann, "it matters not in the least how debasing and repulsive a task may be, it is easy to find people to perform it. But just as soon as labor is set free, then the price of such work will begin to rise. So one by one the old, dingy, and unsanitary factories will come down— it will be cheaper to build new; and so the steamships will be provided with stoking machinery , and so the dangerous trades will be made safe, or substitutes will be found for their products. In exactly the same way, as the citizens of our Industrial Republic become refined, year by year the cost of slaughterhouse products will increase; until eventually those who want to eat meat will have to do their own killing— and how long do you think the custom would survive then?— To go on to another item— one of the necessary accompaniments of capitalism in a democracy is political corruption; and one of the consequences of civic administration by ignorant and vicious politicians, is that preventable diseases kill off half our population. And even if science were allowed to try, it could do little, because the majority of human beings are not yet human beings at all, but simply machines for the creating of wealth for others. They are penned up in filthy houses and left to rot and stew in misery, and the conditions of their life make them ill faster than all the doctors in the world could heal them; and so, of course, they remain as centers of contagion , poisoning the lives of all of us, and making happiness impossible for even the most selfish. For this reason I would seriously maintain that all the medical and surgical discoveries that science can make in the future will be of less importance than the application of the knowledge we already possess, when the disinherited of the earth have established their right to a human existence."
