A quote from James Madison

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.

— Speech in Congress [April 9th, 1789]
