Industrial Use

Famous quotes containing the word industrial:
“I know no East or West, North or South, when it comes to my class fighting the battle for justice. If it is my fortune to live to see the industrial chain broken from every workingman’s child in America, and if then there is one black child in Africa in bondage, there shall I go.”
—Mother Jones (1830–1930)
“Dead power is everywhere among us—in the forest, chopping down the songs; at night in the industrial landscape, wasting and stiffening the new life; in the streets of the city, throwing away the day. We wanted something different for our people: not to find ourselves an old, reactionary republic, full of ghost-fears, the fears of death and the fears of birth. We want something else.”
—Muriel Rukeyser (1913–1980)
