When I read "Decline and Fall of the Roman Empire", what struck me was the slowness of the decline. Most citizens did not realized that their society was in a decline, looking towards their glorious past. Even when Alcaric sacked Rome, Romans believed they still had a functioning Empire.
Mr. Lees posits an interesting paradox: far too many citizens cannot vote wisely. Hence, the political parties caters to these citizens rather than "the wise." If we are to extrapolate into a wiser democracy, then we have take many citizens off the voter list. Big questions: Who Goes? and Who Decides Who is Going?.
In Tiered Democratic Governance, all citizens get to vote. But instead of trying to vote based on the issues, citizens vote make their best guess of who--in their neighborhood--exemplifies good character and capacity for governance.
The TDG is a much different. It allows all to have their say and all vote more wisely than they had in the past.
