After brunch?
It's an unanswerable question, it's just, democracy isn't all that. You've people not voting (thus without a voice), people voting with their hearts and not their head (Obama as a Blackman, Labour as "I've always voted Labour"). Not to mention the fact people will vote for unenforceable policies that seem better if given a chance(lower taxes for better service). The short of it is: people are fickle (and sometimes stupid).
“The best argument against democracy is a five minute conversation with the average voter.” Churchill.
My brother had an interesting idea on Democracy v2.0
As you said, everyone has equal vote on everything at the moment.
This doesn't really sit to great, as surely people with more knowledge/experience/understanding of certain things should have a greater say in them.
Why should the vote of an Economics major on the topic of Economic be the same as Jimmy the street sweeper?
How about having voting points, giving everyone a say on everything, but people who know more about things more votes for that topic?
I am just glossing over his idea, but that's the general feel of it.
