It can be, when it isn't hamstrug by stupid regulations.
In the US the government tends toward being ineffective because it typically isn't allowed to do much on its own. For almost everything it hires contractors to execute a function and then serves as oversight for the contractor. The only real exceptions I can think of to this outside of the military are the postal service, the forest service, and the FAA. All of which are pretty notably effective considering the depth and breadth of the service they provide, and provide high quality, long term employment.
My wife meant to take my name, but then we never did the paperwork. So we just left it.
