From time to time there are proposal similar to yours, which I agree they are better than what we have right now.
Really? I looked and I couldn't find anything like this. Do you have a link?
The main problem is not which of our "alternative democracy system" is better, but how to apply them. Politicians around the world wouldn't like the idea to give the power back to the citizens and will not approve any of these ideas in the Congress.
Why especially would this change things for Congress? You know it's a majority vote here in the USA, right?
