I think a lot of these things boil down to demographics. What societies make the most dynamic changes in the shortest times? My theory is that it's ones with large-base demographic pyramids. Once you become vertical or inverted (like Japan a couple decades ago, the US and most of europe, China soon) you start to become more conservative as a society. Things change more slowly, maybe not directly in terms of politics (meaning things may not swing far right) but in terms of the actual look and feel of society.
