If you look at the currently-active administrators of Wikipedia, they all have their little fiefdoms of "owned" articles, they all know how to play the system (and all protect each other when questions are raised about their behavior), and so the chance of needed change happening has a statistical probability rapidly approaching zero, and likely today so small today as to be inexpressible in 32-bit floating point math.
That the admins have little protected fiefdoms is very true. On the page for Queen's "Bohemian Rhapsody" there's a long psycho-sexual interpretation of the song that is, at best, tendentious. Somebody in the talk page a few months before had suggested removing it, and I agreed in the talk page, without changing the article. The guy who added it immediately accused me of being a sock-puppet and tried to get me banned from editing. This guy is an admin. There are plenty of other examples of this.
