An excerpt from Daniel Guérin's anthology of anarchism:
In some textile plants, red and black silk neckerchiefs were produced, overprinted with anti-fascist slogans. These neckerchiefs were put on sale. "How did you come to set the price? How did you work out the profit margin?" asked one foreign, Marxist reporter. "I don't know anything about profit margin," answered the worker to whom these questions had been put. "We looked up the raw material cost in books, worked out running costs, added on a supplement by way of reserve funds, tacked on wage costs, added on a 10% supplement for the Anarchist Militia Committee and the price was set." The neckerchiefs were sold cheaper than they would have been under the old regime. Wages had been increased and the profit margin sacrosanct in bourgeois economics- was put towards the fight against fascism.
