I don't know of any government that's not mismanaged. Some are just worse than others.
You get functional systems through competition, having many choices so that even if one (or 90%) of them are crap, you can go to the one which isn't. There is by definition no competition at any level of government, which is why so many government-managed services are crap. There is also little competition with most big businesses, which is why big businesses are crap. There is plenty of competition among small businesses, which is why you can go to most walkable downtowns and pick a restaurant and it'll be pretty good, or visit most AirBnB hosts and have a decent stay, or look for a favorite YouTube channel and find one that's interesting.
