A couple of interesting thoughts there, Bruce
The single biggest fragility here in our "system" is the deadly combination of a three-year electoral cycle and an absence of the cross-party support that is essential for longer-term projects: infrastructure, financial reform, social reform
Our current, slightly-left, pale-green government has begun some of the work needed to address our awful housing shortage. It will take decades of determined work on several fronts: Building more houses (private and state ownership), attacking profitable speculation, attacking slumlords, limiting overseas ownership, attacking land-banking, developing infrastructure to allow new builds where they are needed, simplifying complicated Resource Consent process to get things done faster . . .
Any one of these is a ten-year process before any real results will be seen. But, since the government's majority is slender, and since all those processes detailed above will reduce income/assets of the ruling classes and threaten businesses, government is likely to get voted out at the next election before it even gathers a head of steam for the necessary work
Centre/right parties agree and understand (privately) that this work is necessary, but also know they won't get back in power if they support such policies - thus no-one in parliament has the balls to organise a long-term cross-party support for necessary reform
The phrase "captured by industry" comes to mind
I have been arguing for years for some kind of benevolent dictatorship. Look at the things the Chinese get done without an opposition to answer to. But look at the awful social, political and environmental fallouts of their actions. "Effective dictatorship?" Yes. "Benign?" No
Maybe Iain Banks and his vision of the future is right and we will have to wait for a Silicone Dictatorship . . .
I too am getting old and tired and increasingly look at the mess and say "Sorry, my days are done. My children and grandchildren will have to deal with this"
