Dear Thomas,
Thank you for your essay.
You wrote: "Modern capitalism has learned how to use political cover to protect itself against Marx's prediction of over-production and under-consumption, by hedging losses and collecting rewards on economic downturns as well as on gains. " That is nicely put. However, the end game is yet to be played.
There seems to be a natural tendency for hierarchical systems of all scales to evolve into existence. Globalization makes this possible on the largest of scales. Somehow this must be discouraged.
Your distributed network of multi-scale variety would be the most stable, yet it does seem to require direction, planning, in order to achieve it. And how can the seed be planted? Wealth is becoming more concentrated, governments more compromised by it, societies slowly impoverished because of it.
Getting "The 85" to come on board seems problematic. I believe they see themselves has harmless, unlike the towering, lumbering giants they are, and no danger to the world economy which supports them. They do not consider Gulliver in Lilliput to be a lesson to them. It may require social trauma to get them to convert, yet they are insulated from it.
Your place for the US in the future global community seems optimistic. I believe the US has, by its recent behavior, disabused much of the world of its ability to be disinterested and impartial in the allocation of the planet's remaining resources. In any case what it seems, and I think this is your thought, the US would/should be exporting is knowledge in how the various localities should best manage their own resources, in keeping, so far as possible, with local geographic and social conditions.
I'm afraid the transition is not inevitable. It may, perhaps, be managed. Though perhaps something like Georgina Parry's 'sanctuaries' is the most realistic outcome.
Interesting and thought provoking throughout. Good luck.
