From the Obama website:
In November, Barack Obama laid out a comprehensive plan to provide all Americans with a world-class education and give our schools a substantial infusion of funds to support teachers and principals and improve student learning. That plan conditions that assistance on school districts developing programs to engage students in service opportunities. Obama and Biden believe that middle and high school students should be expected to engage in community service for 50 hours annually during theschool year or summer months.
No community service = no funding = no education.
Free education isn't free, comrade!
