It does not and cannot work past the tribe level of society.
That's exactly right. Socialism is a system that can work. We all have intimate experience with it - it's how families operate. The bigger, more capable share their wealth with the smaller, less capable within the family. But it can't operate on the large scale. It begins to fall apart with groups larger than the size of a small tribe. Economist EF Schumacher, in his book Small is Beautiful, gave one reason why: you must literally be "brothers" in order for socialism to work, and in large groups, you can't be brothers with everyone. Great post!
Thank you, I will have to check out Schumacher's book. Otherwise I seemed have ruffled a few feathers with this post!
