In the 1970s the Mexican government acted to alleviate rural unemployment by supporting the migration of able-bodied men. Millions crossed into the United States to find work that would help them survive as well as sustain their families in Mexico. They took low-level positions that few Americans wanted and sent money back to communities that depended on their support. But as U.S. authorities pursued more aggressive anti-immigrant measures, migrants found themselves caught between the economic interests of competing governments. The fruits of their labor were needed in both places, and yet neither country made them feel welcome.
