The full quote: “Arouse, ye slaves! Declare war, not on the capitalist, but on the capitalist system, and if it should be your fate or your fortune to suffer in years to come, that suffering will not be the result of your own deliberate act. I am for the freedom of the working class. Though my heart yearns for the freedom of men, I am powerless. Only the working class itself can achieve its emancipation. The workingman who is not yet awakened, who has not yet realized all his class interests, is a blind tool, the willing instrument of his own degradation, and thousands of them on the 4th of July, when reference is made to the capitalist flag that symbolizes the triumph of capitalism only, thousands of these wage slaves will applaud their own degradation. What is wanted is not a reform of the capitalist system, but its entire abolition.” https://inthesetimes.com/article/fourth-july-eugene-debs-socialism-flag-independence-day
