There are other societal benefits of gap-year service, be it military, civil defense emergency services or community support. If every citizen of every gender was required to do that 14 month (July after grad until August before college, university, work or family begins cohesion is developed that will reduce a lot of the tribalism (ethnic race or nationality based) present in most multicultural societies.
Nevermind just the Starship Trooper-like franchise (although it has it attractions...) it gives individuals a chance to experience a little bit of real (non academic) life, develop a work ethic, discover their abilities/desires/hates, and provide a whole population entry-level skill pool to call up if needed and refresh/upgrade/specialise.
But no exemptions for the connected etc. EVERYBODY serves in some capacity appropriate to their physical and mental capabilities with an apptitude evaluation based sorting into what type of service done before choice of specific trades etc is allowed.
