It may not be called a 'paradise', but I have heard of communities that act incredibly civilized and share their resources among themselves. All of the things you listed are part of this community as they take responsibility for each other. Of course they usually are small by comparison, and they don't 'advertise' for good reason. I hope to find the closest thing to it, start one of my own, or eventually live 'at a distance'. I simply don't like the world drama, and I'm working on reducing my life down to simplicity. And yes, I have kids.
The second option is not to look for this place outwardly, but inwardly. It begins with me. It begins with you. Many organizations believe in a peace that starts from within and we should find those who believe as we do and unite for what want to see in the world. I'm not talking wishy, mishy--my circumstances for the past two years would've made some go on a rampage of violence or depression. I believe--and so provision always comes. I choose peace and that is where I live despite what goes on around me.
Thirdly, Yes, the world is still very lop-sided in granting rights for all people; but for many, we've seen more opportunity than ever to start our own business, barter, access the world via Internet, giving us tons of self-teaching opportunity, etc. Let us take back our rights and privileges and start working for ourselves, among ourselves, instead of idle hopes that we'll someday have a fair government. There are far more common citizens than there is government. If we ban together EVERY time they do something ill, we hit them where it hurts--the Cash. I don't think we know the power that we have. We are allowing media to feed us only the drama, we are allowing the food and gas prices to go up. We have bought into the system and never consider going without for a few days or weeks in order to get their attention. But being angry while standing at the gas pump, or fearful watching the news while drinking your favorite beverage won't make it happen. If we want paradise, let us build it. And deal with anti-paradisers accordingly.
