But, in general, the protective system of our day is conservative, while the free trade system is destructive. It breaks up old nationalities and pushes the antagonism of the proletariat and the bourgeoisie to the extreme point. In a word, the free trade system hastens the social revolution. It is in this revolutionary sense alone, gentlemen, that I vote in favor of free trade.
~Karl Marx, "On the Question of Free Trade" - January 9, 1848
Looks like old Karl could have written NAFTA and CAFTA all by himself! I might send this quote to Rush. If anything could shock him into dead air time this is it.
Free traders might want to reconsider their position when they find out that they brought Karl Marx to the dance.
