Yeah, I think that Mexico, that used to be dominated by a corrupt regime dating from the Mexican revolution is now dominated by the cartels.  I think it's a struggle to keep your kids away from gangs and violence in poor communities here and it's even worse in Mexico.  I think that children who were born and lived their whole lives in the US aren't accepted by the native kids in Mexico or if they are it is a long and difficult transition.  And I think this would make for fertile ground for recruitment by the cartels and along with US citizenship, cultural and language skills these children hold will make them excellent fodder for expanding the cartels up here.  
Oh and my family felt it was offensive, which I guess is something like offensove, back a couple of generations when we were referred to as Wops as means to keep us as the other and not real Americans.  You know, back when a significant number of Italian Americans were involved in organized crime.
