Jeroo Billimoria is addressing the people at the bottom of the world's economic pyramid: children in the developing world. If you want to break poverty, don't start with the adults. Start with the young people," she says. Billimoria, 47, is a Mumbai-born serial social entrepreneur whose latest project is ... to bring hundreds of millions of children into the world's financial system. Billimoria started working with street kids in India 20 years ago, which led her to found ... Child Helpline International, which now operates in 153 countries. "These street kids - 12 to 14 years old - would earn 100 rupees a day ($1.50). And then at the end of the day ... they had nowhere to put the money and feared it would be stolen if they didn't spend it." That led to her next effort, Aflatoun, which encourages financial literacy and savings among children. With her latest launch, Child & Youth Finance International ... Billimoria is aiming to scale up such efforts by enlisting banks and governments. "Currently, it is easier for a child to get a credit card than it is to get a savings account," she says. Products like a simple passbook savings account, or a mobile version thereof ... are difficult to find, even in some of the most heavily banked countries in the world. After consulting with more than two dozen central banks, C&YFI has spelled out child-friendly criteria - no (or very small) minimum deposit, communication in clear language, minimal fees. Then it encourages banks to roll out the products that make sense for them.
