"With all [our] blessings, what more is necessary to make us a happy and a prosperous people? Still one thing more, fellow citizens--a wise and frugal Government, which shall restrain men from injuring one another, shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned..."
T. Jefferson: 1st Inaugural, 1801
