I own myself the friend to a very free system of commerce, and hold it as a truth, that commercial shackles are generally unjust, oppressive and impolitic — it is also a truth, that if industry and labour are left to take their own course, they will generally be directed to those objects which are the most productive, and this in a more certain and direct manner than the wisdom of the most enlightened legislature could point out.
James Madison, speech to the Congress, April 9, 1789
I think all the world would gain by setting commerce at perfect liberty.
Thomas Jefferson, July 7, 1785
