Part of what "works," with prices over gift economies and other systems is how it allows a more seemless trade of resources across the globe. A gift economy is dependent on strong social ties, with many psychology studies show that there are limits to the sort of close bonds we can form with others.

As societies, whether towns grow into cities, or underdeveloped countries enter into global communities, how the social structures we accept and adapt are important to our ability to function and communally grow with those around us. It seems to me as, nominally as a capitalist of some form of another, that by abolishing prices and the like, communism automatically necessitates the reduction of trade and community size back to a focus on smaller more intimate connections.

Do people think this is a fair characterization? Or are there ways that communism address global networking and transferring of resources?
