TL;DR : Westeros is an impossible mix of early middle age vassal politics and imperial rome / early modern bureaucracy, economics†, and excesses of power. And to boot with pretty much a nation state (but a vassal one ??) in the form of the North without the required printing press. (By contrast, Gondor makes much more sense.)
†Also, my own comment : the biology is likely to be very different from ours if the winters are so long - does GRRM ever explain that in the books? (And does he really use multiple "years" for a single season ?)
