P. O. to me: We could rearrange the how the world is organized such that everyone could attain their heart's one true desire if they are only willing to play by certain rules. I think that perfect happiness would be a sufficient motivator for all besides the few that have short-circuits in their minds.
Certainly - if only everyone would abide by the rules, we'd have a Utopia; but Utopia is not possible, because of the people I referred to, sociopaths and psychopaths in the main, but also your average joe (if such a person exists, which I'm inclined to think: Not). How many people do you know who have never broken a law, have never broken a rule? I've never met a single individual who would meet that criteria, and I'm not sure I'd want to, because such a person might possibly be an anemic, lifeless, approximation of a human being, rather than the real McCoy.
We stand at a place in history where hindsight tells us abundantly more than foresight or insight. Nearly 3,000 years of various attempts at Utopia-building, all of which have failed. Some of these attempts were monstrous, such as what we saw in the first half of C20, as well as many a barbarous empire in ages past; some had better luck, as in the UK, the USA, the EU, or places like Australia and Canada.
Now we are witnessing what appears to me as the downfall of the last, and perhaps greatest empire: the USA. What will become of the world when the USA goes down, as Rome went down? The future looks grim from my perspective, though I admit I'm an American, born at West Point, with every advantage, and I've lived my life in relative safety and security thanks to the industry, effort, and sacrifice of millions who came before me, who made it so I could live my life without the fear of having a bomb dropped on my house, or my town or city invaded by a foreign invader.
I don't know if a world stripped of religion is the answer. And the only way a "Utopia" could be established would be through means envisioned by writers like Orwell and Huxley.
