System: Parliamentary Democracy featuring a house empowered with the duties of government and a senate empowered with the duties of state, this could be outlined in vastly more detail but the most important parts are 27 senators per state, 1 representative to a state for every 50k permanent residents, voting districts of no less than five and no more than 9 seats all elected together via Multi-Seat STAR.
Money: maximum price increase per year tied to the federal interest rate to solidify the only motivation for monetary policy being currency stability and sustainable inflation rates.
Written Language: Hangul inspired system with single stroke characters for consonant sounds and closed shapes/loops for vowel sounds, written top to bottom then left to right.
Numerals: Kaktovik but extended to base 36 [0-Z]
Clock System: [0-Z] base 36 hours, minutes, and seconds
Calendar: 4 4 5 quarters with New Year's Eve being an intercalary day, and leap day being inserted before it.
Schooling: Year round schooling, multi-teacher classrooms, IB standard schooling, HEAVY emphasis on keeping students with academic peers, not necessarily age peers (with the caveat of young cohorts, middle cohorts, and mature cohorts, getting their own dedicated campuses so that the teenager who's still only reading at a 2nd grade level doesn't have to feel embarrassed sharing a classroom with 9 year olds), all three meals offered for free to school families (staff and staff families included)
