The closest things will come to in form of 'countries' would be representative councils where information is exchanged and collaboration agreed. The key to living together in peace and prosperity is for people to become more educated and less suppressed by today's corporations and governments. What ever you may call it - in my view 'socialism' is about being social. We need to learn how to lay off our greed and materialistic view of the World. We shouldn't be going to work at 7am just to come home late and consume whatever it is we get bombarded with.
Most people are so busy thesedays simply to work their arses off to be able to live.
In order to find some form of self-fulfilment people then turn to consume stuff simply to get out of it all. A small town somewhere in the south of Germany got so ripped off by their energy provider that they turned around and beat them with their own weapons. The big corporations could do nothing about it and the town has now become self-sufficient and environmentally friendly by using solar, wind and water energy conversion technologies. If we all knew that in fact we CAN be self-sufficient without selling our soul to the Devil, we could all relax a bit more. Self-sufficiency is one major step towards becoming independent again and to start being more sociable to eachother.
