In order to create a Utopian society, the laws, rules, and regulations you expect to have in the future society, should be carefully integrated into society today. Although the nation may not be able to handle turning an entire leaf over at once, it will be much easier to turn over the leaf, a piece at a time. This may take many years, but will be worth it in the end.
The laws need to be enforced, so the individual knows what is expected of him. It will be terribly important to define the use and reason an individual exists. Each individual must use his or her best ability to contribute to the society. As they each do so, the society will thrive, and thus give back to the individual. In order to do this, we must encourage the individual to discover his or her best way to contribute, while doing something they love.
Leaders of the government must be “elected” based on how their moral standard compares with the future moral standard of your expected Utopia. If we expect to have a society that runs by a law of ethics we have decided upon, then we must have leaders willing to run the nation as such.
We must define basic important units of society, such as the government, and the family, also defining how a good government and family runs, and contributes to the society.
It is also important to define realistic expectations of the individual. If you want people to do something, they need to know what that is. If they don't, they either do nothing, do something different, or do something harmful to the society, none of which benefit what was initially asked.
Cognitive dissonance can help a society expand its ideas, and can retain plasticity of the individual and of the nation as a whole. If the society now can get used to hearing new ideas, and deciding freely what their opinion as a whole of the subject is, they allow themselves room to grow. Healthy conflict can be a tremendous help concerning the growth of the nation. There will need to be new ideas to constantly revise the system to fit the betterment of the people, both as individuals, and as a group.
The community needs to be tight-knit in order for the Utopian society to be useful. When the individual is concerned primarily for his fellow citizens in the nation, he wants to protect them. He wants to care for them. He wants the best for him. This bonding process is crucial for a Utopian society to be successful. Unfortunately, it's my belief that each society has it's own way to become bonded, and there is no “right answer” for how to make the society bonded. Perhaps it is needed to make sure only kind language is presented to each other. I do know, though, that if the community bonds in the belief that one faction of society is lower in status than them, the community will ultimately fail. Hate breeds destruction.
Along with bonding, they need to become (slowly) dependent upon each other. They need to begin to watch out for each other, and know they could have someone to fall back on. Although the prolonging of the nation is more important than the individual, the nation is made up of individuals, and thus must care for the individual also. Whether it means lending a cup of flour, or establishing an organization that will care for the lower working class in the society, each faction must know they are not the sole workers, and that, as they are there to benefit society, society is there to benefit them.
A militia, made of the people, must be set up solely for the protection for the individual and the nation. As the citizens gain confidence that the nation will protect them, and as they see that they have the opportunity to be actively involved in that protection, they will be more inclined to keep those in the community safe.
