Ross, plenty have tried, no one has come even close to succeeding!
Quite appart from the USSR and Peoples Republic of China etc, every utopian experiment based on Socialist ideas has failed, largely through internal politics and conflicts.
Even Robert Owen's (the originator of the term "socialist") ideal communities at New Lanark and later communities, particularly New Harmony in the US, failed to become self supporting largely on these counts.
It is interesting of course to consider that these early experiments were all funded by monies gathered from capitalist activities.
