Silvia Federici, Caliban and the Witch: Women, the Body, and Primitive Accumulation pages 63-64

1. The expropriation of European workers from their means of subsistence, and the enslavement of Native Americans and Africans to the mines and plantations of the "New World," were not the only means by which a world proletariat was formed and "accumulated."
   
   
2. This process required the transformation of the body into a work-machine, and the subjugation of women to the reproduction of the work-force. Most of all, it required the destruction of the power of women which, in Europe as in America, was achieved through the extermination of the "witches."
   
   
3. Primitive accumulation, then, was not simply an accumulation and concentration of exploitable workers and capital. It was also an accumulation of differences and divisions within the working class, whereby hierarchies built upon gender, as well as "race" and age, became constitutive of class rule and the formation of the modern proletariat.
   
   
4. We cannot, therefore, identify capitalist accumulation with the liberation of the worker, female or male, as many Marxists (among others) have done, or see the advent of capitalism as a moment of historical progress. On the contrary, capitalism has created more brutal and insidious forms of enslavement, as it has planted into the body of the proletariat deep divisions that have served to intensify and conceal exploitation. It is in great part because of these imposed divisions--especially those between women and men--that capitalist accumulation continues to devastate life in every corner of the planet.
