Jeff Jacoby, chroniqueur au Boston Globe, au sujet du libre-échange:

« Free trade isn’t a battle that countries (or states) win or lose. It is a human right – the liberty to engage in voluntary transactions that leave both participants better off. If John wants to sell something that Mary wants to buy, it should make no difference to the lawfulness of their exchange whether they are residents of different neighborhoods, different states, or different nations. »
