The entire book (Starship Troopers) is presented from the perspective of an 18yo who joined the military for glory.

Now, as for the civil service thing? He basically copied the dual-level citizenship of countries like Rome, where there was a difference between having voting rights and being protected. Heck, even some stock shares operate on a similar principle.
