>>786027no. even in its most bleak versions democracy is still a remarkable social technology for one simple reason:
it encourages the peaceful transfer of power between elites. if you and your fellow elites lose the election to a different faction, you know the best thing to do is lay the groundwork to re-take it in 5 years at the next election.
this sounds trivial but really isn't. every other actually-existing form of national governance is open to succession crises: king, dictator, strongman chosen by the military or oligarchy, all of them cause big problems when they die. you either win or you lose when succession time comes, and if you lose, you've not got much more to lose by starting a civil war or by bringing the whole order crashing down. (one of the reasons dictatorships eventually fall: if your prefered guy doesn't take charge, why not defect to the pro-democracy faction and have those rubes elect you instead?)
the value of peace cannot be overstated. even if non-democratic forms of government were more efficient at administration, 1 civil war every 100 years could easily wipe out all of the gains from that advantage and leave democracy ahead.
