I think we should be clear that we are talking here about a specific form of
representative democracy, not real democracy.
That's important because I know from other posts in other threads that some people, including Scott I think, feel they are democrats in principle, but that in the USA in particular the idea of representation has become so remote that there isn't any genuine feeling of democracy left in the process.
For myself I think representative democracy is the least bad option. It isn't great, but what would be better? I don't want to be ruled by the military, or a self-perpetuating elite, or the rich.
(I think choosing rulers by lottery, for say five-year periods, would be an interesting experiment, but I see that possibility as somewhat remote)
But some of the bad effects of representative democracy can be mitigated by pursuing the principle of taking more decisions at the most local level possible, trying to persuade more people to vote and get involved, and by limiting individual and corporate campaign contributions.
Like Scott I've worked and even stood for a minor party. I think it's important to stand up for and to vote for what you believe in ,even if it doesn't get elected: it has an effect, and smaller parties are often much better informed on specific issues than larger ones.
We are always judging between competing elites. I'm pretty distrustful of suggestions that only 1% of people understand the real issues. Just which 1% is that, and how do you know? In the eurozone at the moment for instance, the ruling elite is to my mind pursuing a lunatic economic policy, and the supposedly uninformed populace of Greece is seeing things much more clearly. But that's my beef
