Famous quotes containing the word industry:
“The Founding Fathers in their wisdom decided that children were an unnatural strain on parents. So they provided jails called schools, equipped with tortures called an education. School is where you go between when your parents cant take you and industry cant take you.”
—John Updike (b. 1932)
