ARTICLE: Money Trickles North as Mexicans Help Relatives, By MARC LACEY, New York Times, November 15, 2009

Interesting phenomenon:

Unemployment has hit migrant communities in the United States so hard that a startling new phenomenon has been detected: instead of receiving remittances from relatives in the richest country on earth, some down-and-out Mexican families are scraping together what they can to support their unemployed loved ones in the United States.

Another sign of the growing irrelevance of the border between the U.S. and Mexico. It is becoming our Durand Line.
