ABSTRACT
International migration is a continuing theme in Mexican history. In the early 1960s, a Mexican author predicted that in the future, blonds from the United States would cross the Rio Grande river to work in Mexico. His prediction was partly accurate: some gray haired Americans retire to Mexico, while large numbers of working-age Mexicans migrate to the United States as the two nations move from a free trade agreement for goods and services toward a common market with free movement of capital and labor. A de facto common market largely exists, mainly legally for the exchange of goods, services, and capital, but often illegally for the movement of labor.
