Reflections on "The City of the Sun"

My first observation of this story is that the city is built on a hill. This reminded me of the concept from the Bible that the church is a city on a hill. This idea of the city on the hill represents the idea that it is where everyone can see and that there is a level of responsibility because of how public it is. The city is well protected by many walls and on these walls there were paintings that were used for educational purposes. A big part of the society is teaching. Even the architecture of the city is all intended to encourage learning. Learning is a big part of this society but so is community. The community it describes is very secure and orderly. The part of the story that was not very utopian was that the state controlled everyone and there was the idea of an elite class. The Genoese traveler was very intrigued and impressed by the lack of crime and poverty in the city. There is no private wealth and everyone follows the rules and only attains things as need be. I am not sure where I should draw the line on this subject for my own utopia. How much freedom should there be without human nature taking over and corrupting my utopia? Should there only be community wealth instead of private? Do these kinds of rules and structured things actually make people happy because everyone is equal or do they just take away the rights of humans?
