While it is not in the Chilean Constitution, Bachelet last year (July 2008) signed a law giving housewives and other poor people pensions. It helps a lot of people who were not getting any pension at all.
This quote is from her campaign for president in Dec. 2005.
"Of course housewives deserve a pension," Bachelet said during the campaign. "Who more to say so than me? I'm a professional and a life-long housewife. I know it's hard work."

Chile revamps famed pension system
Some 600,000 poor Chileans will receive monthly pensions starting in July under a law signed Tuesday by President Michelle Bachelet that plugs gaps in Chile’s widely copied private pension system
Bachelet, who signed the legislation on her second anniversary as president, called the measure “one of the most important social reforms in decades.“
The $2 billion a year program covers groups left out by private pensions – the poor and self-employed, housewives, street vendors and farmers who saved little for retirement – granting about a quarter of the nation’s work force public pensions by 2012.
