Neoconservative Senator John McCain has introduced legislation creating a mandatory national service program very similar to Reich's proposal. It is not surprising that both a prominent progressive and a leading neocon would support mandatory national service, as this is an issue that has long united authoritarians on the left and right.
Proponents of national service claim that young people have a moral obligation to give something back to society. But giving the government power to decide our moral obligations is an invitation to totalitarianism.
Mandatory national service is not just anti-liberty, it is un-American. Whether or not they admit it, supporters of mandatory national service do not believe that individuals have "inalienable rights." Instead, they believe that rights are gifts from the government, and, since government is the source of our rights, government can abridge or even take away those rights whenever Congress decides.
