We don't need an alternative.But to suggest that anyone holding this view should have a nice sound bitey 'alternative' system is unrealistic. The complex interplay of history, culture and power has led to such a system - it's unlikely that a ready-formed alternative could be proposed in a few neat sentences.
We have a system whereby you can put your ideas to your peers, and if they like them, they will give you a mandate to implement them. Everyone has a equal say, and you get to vote in secret so that nobody else knows how you voted.
How much simpler and straightforward could the system be?
The problem is that a lot of people don't like the ideas what their peers are choosing, or that they using their vote for purposes other than the implmentation of ideas, and therefore proclaim the system to be broken.
Rather than undergo the exercise of trying to convince people otherwise, these same Clever D!cks prefer to lock themselves in ivory towers and throw intellectual spit balls at anyone who submits to playing by the rules.
