Child migration from Central America is not a new phenomenon. An International Monetary Fund study of 2009 attributed child migration to three factors: severe economic inequality, presence of drug gangs and high levels of governmental corruption. The correlation with violence is linear. So is the relationship to drugs. It is no random accident that the three countries - Honduras, Guatemala and El Salvador - from which these children are coming have the world's highest homicide rates and are the countries that experienced the most severe political violence during the proxy Cold War of the 1980s, when President Ronald Reagan supported right-wing extremists in their fight against left-wing extremists. The suppression of left-wing dissent in Central America led for a brief time to right-wing dictatorship and momentary stability, supported by the US overtly, and covertly by the CIA.
More recently, since the 1990s, the escalating bloody war in Mexico between the Mexican Government and the large drug cartels there has resulted in migration of smaller drug groups into these smaller Central American countries. The drug gangs have brought violence and governmental corruption. The children turn out to be pawns in their game, useful as expendable coerced drug mules and resultant casualties. There is a push and a pull. The push is drug gangs pushed out of Mexico into Central America. The pull is the demand of US consumers for illicit drugs.
In response in 2009, a Latin American Commission composed of ex-presidents of Columbia, Mexico and Bolivia recommended decriminalisation of drugs like marijuana to remove the major incentives for violence and with that to change the pressure for children to leave their homes, and risk their lives in the hope of asylum in America, a hope that Congress and the President seek to extinguish to their shame.
