One thing that's interesting is that they "make "every adult responsible for bringing in some cash."" I wonder how they do that. Presumably, they kick someone out if they're too much of a slacker. This is important because it means that they noticed the problem of the "free rider", and were smart enough to do something about it, and had a means of doing something about it. That is why socialism can indeed work on these small scales of people who trust each other, and at the same time it's why I object to socialism on the scale of the federal government, which has no idea how, no means, and no willpower to deal with the "free rider" problem.
Jamestown was founded as commune, with everyone entitled to an equal share of the production no matter what they did. Of course, it was a horrific failure until everyone was assigned an equal sized plot of ground and told that 'come next year, you pay six bushels of wheat or you get corporal punishment.'
That made Jamestown a great success of practially overnight.
