Wow! I think we would all like to come work for that perfect organization where you've found a place. Perhaps I am the only person in the world who has ever heard the phrase "office politics", but, in my experience, as ileight2 says in an earlier comment, internal politics can supersede any other consideration (including money!) in any country, market, organization, and time period.
I've found myself, peers, superiors, etc. to be on bell curves with respect to sharpness, being open to new ideas, articulateness, being able to see through buzzwords and BS, etc. Some people are good in some areas and not quite as good in other areas. Pair a "used car salesman" peer (articulate, not so bright, looking to their own advantage) with a "gullible buyer" superior (not so sharp, can't detect that they're being played) and your "better-suited" ideas that rise to the top truly are mediocre, bad, or outright wrong with respect to whatever characteristic "better-suited" applies. Of course there are examples of good ideas being well-received and acted upon, but don't pretend that only the cream rises to the top or that there are only isolated instances of the dregs rising to the top.
