Harris Rosen has been a key player and innovator in the hotel industry for decades. But he's also a social innovator. Twenty years ago, he began the Tangelo Park Project. Rosen "adopted" a Florida neighborhood struggling with drugs and crime. He set up pre-school centers throughout the neighborhood using residents who were trained and equipped for early childhood education. Every child attends for free. And every child who graduates from high school and is accepted by a college or vocational school has their tuition paid 100%. The results have been dramatic. High school graduation rates, which had been below 50%, have been near 100% for years. And college graduation rates are approaching 80%. Crime is down 65%. So why is no one using this idea elsewhere?
