Republicans know that if you could not trade you would have to make all the goods and services you consume by yourself.Every single nail in the couffin of Marxism/economic (or any other) ignorance will be good for Guatemala or any other part of the world.
We have had growing free trade, despite Democratic insanity, for 200 years. Unemployment is now at 4.9%, a 30 year low. Homeownership is at an all time peak, average home size is bigger than ever, $3000 TV sets are now common...
Of course the politically insane lefties oppose that.
When will people learn that the same ideologies that produced Hitler's National Socialist German Workers Party, Mussolini's anti-capitalist Blackshirts, Stalin's Union of Soviet Socialist Republics, Kim Jong Il's Democratic People's Republic of Korea, and the takeover of Mao that gave the world a Red mainland China, and others, are precisely the last people in the world to be listening to when it comes to when it comes to avoiding social and political crisis? I visited this leftwing StopCafta site, and it was very creepy to watch them emphasize thousands of job-losses (through comptetition) while ignoring millions more employed as a result of NAFTA.
I don't know about the Mesa Global group, but if they oppose economic reforms more than they actually help to bring them about, then I see no use in citing them.
