Tough choices are needed to bring down spending and the deficit. But eliminating national and community service programs would strike a devastating blow to nonprofits, communities, and millions of vulnerable citizens at a time when social needs are growing, unemployment is high, and Americans are eager to serve. National service is a smart investment because it relies on millions of citizens—not bureaucracies—to solve problems. It taps their energy and compassion to mentor at-risk youth, care for frail seniors, assist the jobless, re-engage wounded veterans in meaningful work, rebuild after disasters, and teach and tutor in our lowest performing schools. The five million citizens in national service expand the reach and impact of more than 70,000 nonprofit and faith-based organizations—strengthening schools, food banks, homeless shelters, health clinics, and other groups as they face soaring demands due to the economic downturn. The crisis in the nonprofit sector is severe and citizens can help fill the gaps through national and community service efforts.

City Year is mobilizing young mentors and tutors in our lowest performing schools to prevent disadvantaged youth from dropping out, a national epidemic affecting more than one million youth every year and resulting in higher rates of unemployment and crime. Teach for America is not only sending talented teachers to underserved areas, but also creating the will to transform our failing schools. National service also provides an economic boost at a time when our country needs one. With record unemployment rates among young adults, national service performs a vital function—putting the unemployed into productive work for a year to help address the nation's needs, while giving them the skills and training to transition into full-time jobs.

The cost to the federal budget is a rounding error, as tens of thousands of young adults serve their country in exchange for a below-poverty living allowance and small educational award to defray the costs of college or graduate school. AmeriCorps is a better bang for the buck than Pell Grants and other federal programs because it requires a year of national service in exchange for public benefits. National and community service opportunities not only enable young people to work on our greatest challenges, but also transform the lives of those who serve. We've seen countless examples of how service shapes lives—turning them away from gangs, drugs, and dropping out toward a positive path of graduation, work, and active citizenship. Young people become citizens not spectators. Nearly every president since George Washington has envisioned an active role for citizens in keeping our democracy vibrant and addressing the nation's challenges. When Franklin Roosevelt worked to combat record unemployment during the Great Depression, he created the Civilian Conservation Corps that put 3 million young men, who were out of school and work, into productive service to strengthen our public lands. The results—which included the planting of 3 billion trees and providing drainage for 84 million acres of public land—were stunning.
