Hi Muir,
When we speak of elites there are two different groups here. Those pulling the strings in government and the media are the rich, and they do so in order to preserve and grow their wealth. That's another topic for another day.
In science though, the elites are really just the hive mind of the scientific community that is overloaded with left brain dominant personalities. You can find the same thing in churches: A central mythology at odds with the facts; (String theory, many worlds theory, the big bang, etc.) a strong fight against new ideas that disrupt the currently agreed upon viewpoint and shunning of outliers within the group who think differently.
That's how I see it, anyway.
I agree with everything you are saying here, but i just want to add a further dimension to this
The first elite you mention is 'the rich' then you mention the hive mind that is resistant to change, but i want to make the suggestion that unfortunately the two are often intimately linked.
We know that history is written by the victor. In science funding for research is allocated by the rich, findings protected by patents, pieces hand picked for publishing, secrets withheld, and often research is used by the rich to justify their aims which is why it seems that both sides in a debate will often be able to get 'experts' to support their claims.
There is ongoing debate over the causes of climate change for example. I recently spoke with someone who works with the scientists in the Antarctic and thought i had a great opportunity to find out the latest view straight from the horses mouth, but i was informed that the scientists are themselves pretty much split down the middle.
We know that think tanks of the extremly rich for example the Club of Rome (
http://en.wikipedia.org/wiki/The_Club_of_Rome) which first met in the Italian villa of David Rockefeller have exerted a lot of influence in the debate for example through their 1972 paper 'The Limits of Growth'
Concerning churches of various hues, i really see them as another arm of the elites. They have always been intimately linked in a hierarchic system of control eg 'the three estates':
http://en.wikipedia.org/wiki/The_three_estates, which may even be a far older model of societal control from the top, dating to the proto-indo-european phase as suggested in the trifunctional hypothesis:

It seems if you want to control the public you need to put various apparatus in place. You must be able to control their mind, their body and their spirit.
