I've always had a fringe opinion of how such people come to be influential. The fact is that although we as a society are progressing with regards to general knowledge and standard of living, as individuals there are many who do not or cannot keep up. Just as there is great income disparity today there is great knowledge disparity. Someone like Greene represents that group left behind as far as knowledge and the status it brings is concerned. She and those like her benefit generally but their influence has waned within the society as a whole. The resulting insecurity brings about a defense of their ignorance.
It's a bit off-topic but this reminds me of an interesting point I gleaned by reading Cunliffe's accounts of early Europe, or Homer's Odyssey.
For the noblemen of Bronze-Age or early Iron-Age Europe, the goal of life was less accumulating wealth, than accumulating knowledge. Heroes were renowned for their adventures and heroic deeds, not for the amount of gold in their treasury.
Contrast this with post-rational America where pure Wealth is King, where nothing matters but money. Money money money.
