>In Starship Troopers, the key difference between a citizen and a civilian lies in their rights and responsibilities within the Terran Federation. Citizenship is earned through Federal Service, which typically means military service, and grants the right to vote and hold public office. Civilians, while enjoying legal protections, cannot vote or hold political office

That doesnt sound so bad...? It stands to reason that the portion of the population willing to fight and bleed for the nation should hold higher degree of control over its fate...
