42 years of the nationalization of copper in Chile

Yesterday, July 12, was the anniversary of the nationalization of copper in Chile. Allende referred to the nationalization as the most important act in Chile's history since independence (you can see parts of his speech in this documentary from Telesur here; in Spanish). Even though the government of the military coup (1973-89) weakened the nationalization, it was ultimately unable to revert the process and privatize it. This is the most direct cause of the coup against Allende, and the support from the US intelligence services. In the last decade natural resource nationalism (as noted before here) allowed for better income distribution.
