I think you were emphasizing the participation part? And I agree, but curious to where do you draw the line on what constitutes participation?
Some argue simply paying taxes. Others say it is a list of things perhaps, called "civic duties". Finally, some more extreme believe you have to do it all: attend the town halls, keep up with the times, understand the various debate points, otherwise you are somehow disqualified from playing. (A side note, it has become impossible to keep up with all the ways government affects your life, and this is one of the exact reasons the founders were for limited government. They argued as the responsibilities and roles of government increase, it becomes impossible for the "commoner" to keep up and stay engaged, thus becoming a form of tyranny in of it's own.)
I think it's definitely a gray area, but the more participation, obviously, the better, while still somehow maintaining the ability to serve those who participate little just as equally. Otherwise you become a government of some people, not of all people.
