That's why it's never been done on a large scale, trying to remove a culture which is considered the norm on such a scale would be nigh impossible unless you had people who were born in a vacuum with no other societal or cultural influences which in itself could be considered unethical.
Communism in it's purest form is a nice idea, but I can't see it ever actually being implemented properly.
(btw it's cool the devs have brought the discussion to table and people are talking about it)
You don't think there's any difference between the society we augment for our children then the one we ask them to partake in as adults? Society is merely a social construct created in the present day by our naive understanding of material reality a few hundred years ago.
We teach our children to share, work together, love their neighbours/people around them, that their needs will be provided for but they should control their wants, be kind to everyone they meet, animals should be petted and stroked, hurting people is bad. Then we push them into a society, off our own creating, that's opposite and wonder how they become alienated. The way we talk to children about the environment and how it should be protected, yet we rape and exploit it as if it's an infinite resource given to us by a supernatural being ... as if the way we use it today in our economy is a byproduct for the way it was viewed when religious leaders had more prominence..
It's a society of our own making, a society whose only basis is how we view our material conditions, and we vilify the people who try to explain this to us.
