Racism, xenophobia and unfair discrimination have spawned slavery, when human beings have bought and sold and owned and branded fellow human beings as if they were so many beasts of burden. Desmond Tutu
All my life, I have been driven by one dream, one goal, one vision: to overthrow a farm labor system in this nation that treats farm workers as if they were not important human beings. Farm workers are not agricultural implements; they are not beasts of burden to be used and discarded. Cesar Chavez

Ireland, in breadth, and for wholesomeness and serenity of climate, far surpasses Britain; for the snow scarcely ever lies there above three days: no man makes hay in the summer for winter's provision, or builds stables for his beasts of burden... the island abounds in milk and honey. Venerable Bede
Man has been trained in the same way as animals. He has become an author, as they became beasts of burden. Julien Offray de La Mettrie
