Was sure I heard of this before, then I see it. ''Venus project'' unfortunately it assumes that man is not inherently greedy by its nature, that man is not selfish. It's a cool theory, but I think thats what it will always be, a theory. Also some places are just naturally more abundant than others. Take Japan they basically got nothing and have to import everything. It's like the idea of unconditional giving/sharing, works only if you assume it goes both ways. But likely someone will take advantage of another before we see peace on earth.

People naturally compare themselves to others, their productivity and welfare. This theory doesn't account for any of the psychological factors which capitalism actually does. It recognizes that we are competative and tries to leverage that to get the most out of humans. I don't necessarily agree with capitalism but I also don't necessarily agree with communism. All these theories are great on paper, capitalism, communism, resource based economy. But practically they seldom work out well because being human is more complex than economics and ideology.
