Here is some information on the El Sistema music education system that has been in place in Venezuela since 1975.
"The program is known for rescuing young people in extremely impoverished circumstances from the environment of drug abuse and crime into which they would likely otherwise be drawn. Participants of the program who have begun international careers include Gustavo Dudamel, Edicson Ruiz, Joen Vazquez, Pedro Eustache, L. Miguel Rojas, Edward Pulgar, Natalia Luis-Bassa, among others.
In September 2007, President Hugo Chávez announced on television a new government program, Misión Música, designed to provide tuition and music instruments to Venezuelan children...
On 6 June 2007, the Inter-American Development Bank announced the granting of a US$150 million loan for the construction of seven regional centers of El Sistema throughout Venezuela. Many bankers within the IDB originally objected to the loan on the grounds that classical music is for the elite. In fact, the bank has conducted studies on the more than two million young people who have been educated in El Sistema which link participation in the program to improvements in school attendance and declines in juvenile delinquency. Weighing such benefits as a falloff in school drop-out rates and a decline in crime, the bank calculated that every dollar invested in El Sistema was reaping about $1.68 in social dividends."
