It's no coincidence that an acute sensibility to the condition of animals comes up at the same time as industrialised food and concentration camp sty… - Gilles Dauvé

Managers try to make the workplace safer and less destructive (= more productive) of a precious capital: labour. Animal exploitation duplicates this process. It tends to experiment less on animals in order to get more from them, painfully if it must, painlessly if it can

Animals that kill usually have far more social relationships than those they prey upon.

Communism knows no monster. ... Should abuse occur, the perpetrator would not be ostracized by his fellow human beings. They would not reject the social violator in order to reassure themselves of their humanity by comparing themselves to a non-human human, to a monster. They would be able to recognize what they have in common with him, and to realize that they could have done what he did. And this, we believe, is a much better way of reducing abuse to its lowest possible minimum than any search for normality.
