I’m not sure exactly what a Utopian society would be but I imagine that is one where people look out for and love each other, taking care of each other’s welfare. Where goods are freely shared among people and the needy do not exist, since the plenty that does already exist is freely passed around to those who have less, with good flowing from the rich freely to the masses. Everything done effortlessly with love as driving factor.
Assuming that, I think, it would be possible to make such Utopian society happen by initiating the changes on each of our personal level. E.g., for those who currently have less, in terms of material goods, they may come to realize that they actually have more than those who have in terms of material wealth when they consider the wealth they enjoy from having a happy family (albeit hungry) or a strong faith in God. It may seem then that the society first has to be engineered from the individual’s belief level. Perhaps the materially needy can extend compassion to the rich, in realizing that some rich people may not have the faith and love they experience. I have written in my “What a Bright World This Would Be”, a simple strategy that can be initiated from the personal level.
Nothing can be accomplished en masse without beginning from the individual level, I believe.
There are several attitudes that need to be assimilated to have the Utopian idea that I described possible. A master named Jesus already gave us a glimpse of the type of paradigm shift we need to make in order to make this world anew. It would be hard to go into details of what are needed to get there and what such world would look like.
Based on the context of my experience, and considering my imagination is capable of visualizing such an outcome, e.g. a Utopian society, then I think it would be possible to have one. The only thing would be is that it may take time, not happening in our present generation.
