Famous quotes containing the word universal:
“The poor, stupid, free American citizen! Free to starve, free to tramp the highways of this great country, he enjoys universal suffrage, and by that right, he has forged chains around his limbs. The reward that he receives is stringent labor laws prohibiting the right of boycott, of picketing, of everything, except the right to be robbed of the fruits of his labor.”
—Emma Goldman (1869–1940)
