Many want to overhaul a dictatorship-era private pension system that is widely criticized in a country with a rapidly aging population.

More than 1.2-million Chileans receive a pension that is less than $216 a month, well below the minimum salary of $400. Like Gonzalez, many retirees need to work in the informal sector to make ends meet.
