In biology, the longer the relationship between parasite and host, the smoother for both; because each has learned to cope with the other.

Perhaps the longer the relationship between the elite of a society and the people, the smoother the mechanisms to make people conform? And the more people’s attitudes support compliance?

Are Western democracies stable because they combine well evolved mechanisms and co-evolved attitudes?

And does introducing democracy into other countries disrupt the co-evolution of their institutions and attitudes?
