Famous quotes containing the word industry:
“What more is necessary to make us a happy and prosperous people? Still one thing more … a wise and frugal government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from labor the bread it has earned.”
—Thomas Jefferson (1743–1826)
