A self-made millionaire Harris Rosen adopted a Florida neighborhood called Tangelo Park, cut the crime rate in half, and increased the high school graudation rate from 25% to 100% by giving everyone free daycare and all high school graduates scholarships
Rosen, 73, began his philanthropic efforts by paying for day care for parents in Tangelo Park, a community of about 3,000 people. When those children reached high school, he created a scholarship program in which he offered to pay free tuition to Florida state colleges for any students in the neighborhood.
