I'm not sure, though, how indenturing yourself makes your service "better" than others service. Does it make your service more effective? Do your hours produce more good for the country than equivalent hours served by someone else who goes home at the end of the day? Does a teacher who commits 40 years to serving in the toughest neighborhoods and working with the toughest kids make less of an impact for the nation than the average soldier with a 4 year enlistment? Why?
