Allende had a weak character. He disliked confrontation and so his advisors tried to implement their own policies, and he couldn't turn them away. He should have known better, yes, but ultimately he was more of a puppet than an authority figure, and that was a large part of his downfall.

Shadow Nexus, I understand what you're trying to say, but I honestly can't imagine any kind of Marxist/anarchist large scale scenario that doesn't lead to hoarding and violence. The example that you gave, from Spain, was limited to a relatively small portion of the population, (if I remember correctly) and I've seen socialism work very very well in small communities, but as more people are involved, it breaks down. How can you possibly avoid that?
