Very thoughtful and interesting. The link below illustrates some of the problems highlighted  very well.

Representative democracy is certainly in a perilous condition right now and will probably not get any better until there is quite radical change.

I think the problem may be deeper than anything addressed by electoral reform however.

We treat politics like a service industry where we contract out our need for governance to people who will undertake to do it for us. However, we know that when we contract things out, it is rare to find a contractor who will provide anything above and beyond the terms of the contract. Contactors work on behalf of themselves or their shareholders. They will accrue as much benefit to themselves, or those they answer to, as they can. It is up to us to ensure compliance but the very fact we have contracted out implies that we can't or won't allocate the time, effort or skills required.

The work of people like Oliver Escobar in devising means of Democratic Innovation shows a way forward. It is entirely consistent with C.L.D. values and principles and is underpinned by sound research and exemplified by case studies from around the world.

Above all the factor that is most corrosive of democracy is the gross inequality, economic, cultural and political that pervades the world today. Democratic innovation can begin to address that.
