Are all MPs 'elites'? Are all "experts" elites?
You'll have to ask claig for the proper definition of "elite"
But for my posts above, I've been thinking of it in terms of the powerful, privileged and wealthy.
FWIW no, I don't think all MPs are "elites", though several are (Eton anyone?). Many MPs are of course ordinary hard-working people doing their job for the benefit of others.
I see intelligence and academic specialism as a very different (and positive) definition of "expert" and "elite", unrelated to wealth or power. The professor working to find cures for disease, the playwright who's the new Shakespeare, or the scientist who discovers a new planet.
Now and again it becomes clear that some of the most powerful people in the world aren't necessarily the most intelligent. Some are, but not all. So there's another definition of "elite", i.e. those with money, influence and connections. They are the "elites" who benefit from big business, big banks, political power (official and unofficial), social connections, international entertainment, corporations, influence on the media etc. I'm not convinced they think about "what's in it for the ordinary citizen?" when making decisions, above "how much money can I make?"
