"It seems to me that at least one of Marx’s observations is true: every minute devoted to the capitalist production process, every thought contributed to the industrial system, further enlarges a power that is inimical to nature, to culture, to life... Nationalism is not flown in from abroad. It is a product of the capitalist production process, like the chemical agents poisoning the lakes, air, animals and people, like the nuclear plants radioactivating micro-environments in preparation for the radioactivation of the macro-environment.
As a postscript I’d like to answer a question before it is asked. The question is: “Don’t you think a descendant of oppressed people is better off as a supermarket manager or police chief?” My answer is another question: What concentration camp manager, national executioner or torturer is not a descendant of oppressed people?" -Freddy Perlman, The Continuing Appeal of Nationalism
