In the '60s, perhaps the most remarkable change agents were the civil rights workers and antiwar protesters. Today the most remarkable young people are the social entrepreneurs, those who see a problem in society and roll up their sleeves to address it in new ways. Take Andrew Klaber, a 26-year-old playing hooky from Harvard Business School, who is an example of the social entrepreneur. He spent the summer after his sophomore year in college in Thailand and was aghast to see teenage girls being forced into prostitution after their parents had died of AIDS. So he started Orphans Against AIDS, which pays school-related expenses for hundreds of children who have been orphaned or otherwise affected by AIDS in poor countries. This NY Times article reflects on the growing numbers of young people finding creating ways to serve the world.
