As has been explained in more detail by more capable media critics than me, Harry Potter's overall narrative arc is about restoring bureaucracy, not overthrowing it. The problem are never the systems but individuals abusing them because they're evil (with little motivation given). If anything, framing it as "the bureaucracy overthrowing the hero" (or the hero making peace with the system, for a less dramatic interpretation) is only wrong because this implies the hero was ever at odds with the system to begin with. The system is never questioned (except by Hermione, who is portrayed as annoying an naive when she does it), only individual bad actors are identified defeated. The ending of Harry Potter does not have wizards living openly alongside muggles, house elves liberated, mutual respect and trust between wizards and goblins, or the abolition of the Ministry. Instead it shows the next generation of students getting to experience the same exciting start in their train ride to Hogwarts with the implication that this time, things will be different because the evil people are REALLY gone this time.
