In my opinion, 'The Giver' by Lois Lowry presents certain elements that could be seen as a description of a utopian America, although it has its complexities. It explores concepts of community and order, but also raises questions about the cost of such a society.
I think 'Brave New World' by Aldous Huxley might provide some insights into a potential utopian America. However, it also shows the darker sides and potential pitfalls of striving for an overly controlled and 'perfect' society.
Well, one could argue that 'Looking Backward' by Edward Bellamy offers an interesting take on an idealized America.
