…[It] is evident [obvious] that the state, and if necessary the nation, has got to possess the right of supervision and control as regards the great corporations which are its creatures; particularly as regards the great business combinations [corporations] which derive [develop] a portion of their importance from the existence of some monopolistic tendency [desire for no competition]. The right should be exercised with caution and self restraint; but it should exist, so that it may be invoked if the need arises. —President Theodore Roosevelt, 1901
