Interesting stuff on participatory economics. One system that always interested me is that of the Incan Empire. They had no money, no traders and no marketplaces yet were building large scale Public works across their empire. From what is known there was little if any Poverty yet the region they were in was not condusive to large scale agriculture given it was not overly fertile.
The First nations “Gift economy” also thrived for a long period of their history.
Digs in Turkey have turned up a culture that existed for generations in Çatalhöyük wherein there appears to have been no noble or priestly cast and where women and men were seen as equals. The society was eglatarian as far as can be determined.
Reading that article on participatory economics I tend to feel that the Incan model was something like it.
I always read the supporters of the current system claim TINA as if the system called Capitalism as we know it has existed since the dawn of time and no other economic model lasted as long. This simply false as it has really only been around for a few Centuries and in that time has helped to fuel environmental destruction on a scale never seen before. I just can not deem it a success. To me it very much like running up a Credit Card to its max to buy stuff NOW while putting off the payback that needs to happen in the future.
