Michael Walzer one said that this kind of economic planning produced a "socialism [that] means the rule of the men with the most evenings to spare", and thats essentially true here, when talking about the various organs that would arise to fulfill such planning functions. In the novel The Dispossessed, the bureau that assigned or offered jobs, ostensibly in a total neutral and machine-controlled way, had its own internal logic that most of the residents simply deferred to. A number of utopian communes in America found themselves in the ridiculous situation of constantly having to discuss even the smallest thing and negotiating their "labor hours" to be able to meet all the mandatory discussion times.
This will be especially true for things that require complicated logistics, such as the transportation industry, especially the aviation sector, but less so for products that can be translated from raw material to finished product in one factory. Another question is, to what extent do we want to rely upon factories so specifically built for the needs of capitalism (and hence over-production), as opposed to say changing them or tossing them overboard in favor of more decentralized production methods.



Although I certainly disagree with many of his beliefs, I found mutualist writer Kevin Carson's thoughts on economic federalism interesting:

This seems kind of depressing, but I guess it doesn't necessarily have to be seen as such. The Argentinian example of autonomous worker-owned firms is a source of inspiration, acting on a free market typified by cooperation and limited "competition" (in the non-negative sense).
Thoughts?
