Read ten pages of "Democracy: the God That Failed" and see if you still feel that there's so little substance to what we believe.
Even before reading it, I already agree that democracy does not work the way people originally thought it would, and some pretend it works even today. (People voting to get money from their neighbors' pockets. Idiots who know nothing and want to learn nothing, but their vote is just as important as Einstein's. Media ownership being the critical factor in elections.)
That just doesn't give me enough confidence that my solution would be better. Let's say it would avoid some specific problems of democracy successfully. How about new problems? (Or merely repetition of the old ones, enhanced by the modern technology.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
