That's also the "endgame" of pure democracy, and of basically every other "pure" form of government. (Classical Western philosophers knew this very well, BTW - they had very detailed models of how these violent crises happen, and how they lead to different forms of government in turn, with their own inbuilt instability.) It's one reason why sustainable government is pretty much always based on a variety of institutions that enable ongoing checks and balances among different organized interests. It's why we have republics, and not pure ("direct") democracies.
