I agree that execution is the key, and I don't have the answers for a lot of the questions.

I guess we (humans) will never achieve the equality that everyone agrees to, because every one has his or her own idea of equality, but maybe that shouldn't prevent us from trying.

You have a very strange idea of "everyone". I never agreed to economic equality.

Yeah that's one view of equality (by not agreeing with the concept from the start), and why I said there is no single answer every one agrees to.

>maybe that shouldn't prevent us from trying.

When you're planning on taking the money for your utopian pipe dream from other people by force, you really ought to have a better justification than "it doesn't hurt to try!"
