As for exporting the population - remittance is Mexico's 3rd largest Gross National Product. It's well over 3 bn a quarter and follows only oil export at 5 bn and Assembly for export at 4.5 bn per quarter. So that is exactly what the Mexican government does. That's all money made here in the U.S. but spent in a foreign country. Remittance is heavily relied on by the Mexican Government and strongly dependent on undocumented workers in the U.S.
