We may have to disagree at this point, but there are 100 billion worth of dollars, which is going to create some pretty strong economic interests. Are you using "entrenched" in a historical sense? I suppose I'm using it more as a substitute for "heavyweight".
Anyhow, I don't think it's a stretch to believe that there are strong economic powerhouses controlling billions of dollars trying to promote the green movement.
I'm not totally sure if the other side of the coin is particularly relevant, unless it's the case that politicians are all already bought and paid for by fossil fuel interests, and thus not available to be bought by newer "green" economic interests.
