What makes the US more chaotic (and UK to some extent and probably more) is the political system first-past-the-post which does nothing to promote collaboration. Quite the contrary the winner does its best to crush every sprout of the loser to make his future win more likely. Now if you had a few parties which would be forced to forge alliances to govern, they would probably govern in alliances in the following terms as well so some of the politics for sure get carried over. But, such ideas help now nobody, the current system is how it is.
