You are either a troll, or have never worked a day in your life. How's the trust-fund?
Given contract law, can you explain how the courts are constantly filled with people suing others over breeches of contract that was formed under the aegis of "free-trade"? This is part of the overwhelming empirical evidence that exists to demonstrate that "Free Trade" is only an academic subject that totally ignores human nature and pretends that which is demonstrably false - that people are inherently good and always seeking perfect morality.
What an ignorant question. You can bet if I promised you a case of your prozac in exchange for an amount equal to your welfare or disability check and you didn't pay me, I would sue. A contract is actually PART of the entire trade process. Are you really the best your side has?
