What Bill Gates' Kids do with their Allowance The rich are different from you and I, but they still want to give their kids an allowance. So what do the world's richest man's kids do with their money? Melinda Gates came to TIME's offices to talk about her new focus on women and children and especially on contraceptives, but she spilled some secrets about how she tries to get her kids to be purposeful with their money. First of all, she tries to be true to her values, to articulate them and live them out. Then, they do a lot of volunteering together, at "whatever tugs at their heartstrings" says Gates. And of course, they've traveled with her. "They have that connection I think to the developing world," she says. They see the difference a flock of chicks makes in a family's life. It's huge. Read the 10 Questions with Melinda Gates here Gates has always made a point of getting into the streets and poorer neighborhoods when she travels for meetings and conferences. And sometimes she takes her kids. It's there, she says, that she meets mothers who tell her that their biggest struggle is having so many children. Although Gates was raised Catholic, she is heading up an initiative to get family planning information, contraceptives and services to 120 million more women by the year 2020. That includes new technology, better delivery system and a lot of education, including for men. She's similarly rigorous about her home life. Her kids save a third of their allowance and designate a charity they'd like to give it to. They can also list donations to charities on their Christmas wish list. As further incentive, their parents double whatever money they've saved. Which means they may be the only children in the world to get a matching grant from the Gates Foundation.
