I will agree on your last sentence. So question is do you think people are inherently good or bad by nature? Good example that sticks out is this....child (age 3) takes caramel roll off counter parent see this child hides the roll jumps off chair runs to parent. Parent ask did you eat a caramel roll? Child says NO! I didn't! to the parent no hesitation on the childs part with the evidence smeared on the childs face. At age 3 a child will lie... not influenced by society at that point i would say, but yet hmm a lie from a little 3 yr old. So good or bad are people in essence i would say bad.Yeah, I don't agree with Marx's view of human nature. Clearly our nature is partly determined by the society around us, but not entirely, not to the extent that he believed. Still there could be possibilities for a better society, workers owning the means of production, if we could start to build it, make efforts in that direction. I'm skeptical that it's actually possible to overcome the entrenched interests which keep the capitalist system alive, revolution is not the answer. But trying to live in community, co-operate rather than compete, build non-hierachical structures, this is a useful project. Actually it's generally anarchists rather than socialists who attempt this.
Accepting capitalism just because we don't like communism is (again) the product of a false dichotomy.
