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)
“A few ideas seem to be agreed upon. Help none but those who help themselves. Educate only at schools which provide in some form for industrial education. These two points should be insisted upon. Let the normal instruction be that men must earn their own living, and that by the labor of their hands as far as may be. This is the gospel of salvation for the colored man. Let the labor not be servile, but in manly occupations like that of the carpenter, the farmer, and the blacksmith.”
—Rutherford Birchard Hayes (1822–1893)
