I appreciate the moonshot thinking, but I don’t think this is a realistic framework for human civilization. We already live in a society in which not everyone contributes (rich and poor), and it’s problematic. Inequality and resentment are inevitable when some contribute (or feel like they contribute) more than others. I think humans are generally not evil, but we are also quite fickle. I think you’re describing the dystopia of The Hunger Games from the perspective of a Capitol resident. :)
