Famous quotes containing the word trade:
“The girl must early be impressed with the idea that she is to be “a hand, not a mouth”; a worker, and not a drone, in the great hive of human activity. Like the boy, she must be taught to look forward to a life of self-dependence, and early prepare herself for some trade or profession.”
—Elizabeth Cady Stanton (1815–1902)
“We are the trade union for pensioners and children, the trade union for the disabled and the sick ... the trade union for the nation as a whole.”
