You seem to be
using the word "cabal" here in a sense that
is neither derogatory nor ironic. I find that highly disturbing.
You may find it disturbing, but the truth is that there are people like
Jimbo who can make high level decisions, and there are sysops that have
more power than ordinary users. Many of these decisions already happen in
places that most people don't know about (e.g. the mailing list). Glossing
over the truth doesn't make it go away: there is a Wikipedia cabal.
Cabal implies secrecy, what we have here is a benevolent dictatorship.
