“ … but outside, beyond the broad seas, there are the markets of the world, that can be entered and controlled only by a vigorous contest, to which the habit of trusting to protection by statute does not conduce.
At bottom, however, the temperament of the American people is essentially alien to such a sluggish attitude. Independently of all bias for or against protection, it is safe to predict that, when the opportunities for gain abroad are understood, the course of American enterprise will cleave a channel by which to reach them.” --- Alfred Thayer Mahan
