"The surprising reality, however, is that Mexico's immigrants--a population exemplified by the half-million or so Poblanos living in the New York area, but with another 500,000 concentrated mainly in Los Angeles, Houston, and Chicago--fuel a complex economic dynamic, both here and at home. In taking on menial work in this country, Mexicans have not only raised their standard of living and that of their families, they've also created a flow of capital back to villages across Mexico, especially towns throughout Puebla. That transfer of wealth--around $17 billion last year, double what it was only four years ago--has transformed life across the border, where new housing, medical clinics and schools are under construction.
