How come none of you trade restrictionists want to answer the question about why restrictions are good around the US border. But not good around state borders?
I've answered it many times, narby. Where've you been?
Within our domestic borders, our domestic industries compete against each other on a level playing field, all subject to a common set of laws and regulations defined by the jurisdictional boundaries of our Constitution. Industries in other nations are not bound by those same constraints. Indeed, they seek to turn those regulations against us for their own profit. Why is it that you seek to undermine our domestic industries as well?
Do you mean in the sense of "international commmerce" or "interstate trade"?
