But he has fallen far short of his campaign promise to eradicate poverty by the end of his term in 2014, and Chileans perceive the wealth gap as wider than ever, Lagos said.

Along with mining, Chile enjoys strong consumer demand and profits from exports of salmon, forestry, wine and fruit. During a recent visit to Santiago, International Monetary Fund Director Christine Lagarde praised Chile for being one of the fastest growing economies in South America and keeping unemployment at historically low levels while controlling inflation below a target 3 percent.

"Chile has been a successful country and there are many reasons why Chileans should be proud, but the country remains largely unequal despite progress," said Patricio Navia, a Chilean political scientist who teaches at New York University.

Students are demanding an end to the decentralization of education in Chile, which has created a system of failing public schools, expensive private universities, unprepared teachers and pricey student loans.

Environmentalists are demanding an end to the privatization of Chile's water, another legacy of the Pinochet era.
