- The Economics of Immigration Reform
Emile Schepers, People's World
The rationale for NAFTA (North American Free Trade Agreement), which came into force Jan. 1, 1994, was Ricardian (after the Anglo-Italian classical economist David Ricardo, who thought that each country should specialize in the production that most suited its climate and other characteristics).
Much of Mexico's rural population was engaged in maize and wheat farming, which is much more productive in the vast plains of the central United States and Canada than in Mexico's more rugged terrain. So the idea was to push the grain farmers off the land and move them into specialized fruit and vegetable farming, and into manufacturing which was supposed to be attracted to Mexico by the cheap labor of displaced farmers.
