Everyone has their own idea of what a perfect world would be, hence the world would never be perfect for all people. That said, my idea of a perfect world is simple. It would be a world where at least everyone's basic and safety needs were taken care of. People would not have to worry about food, shelter, clothing, healthcare, insurance from catastrophe, or other protections. All that would be taken care of. Everyone could thus focus on the higher needs on Maslow's hierarchy. Psychological needs, self actualization and peak experiences. Sure, there would still be unhappy people, but much more than in today's world, people would actually control their own destiny. When you have to worry about losing your home, being able to afford to put food on the table, or how you are ever going to get a necessary surgery, you don't have much control over anything. But if you have those first two tiers of needs met, you can than focus on building friendships and find challenging work to fulfill your psychological needs, building a career and nurturing relationships that will help you move toward self actualization and form those peak experiences. Of course, people could still make poor decisions, failing to then meet those higher needs, but at least their bellies would be full, they would have a roof over their heads and not have to worry about losing those two things if they got sick, or encountered a natural disaster.
