Answer:
There are different definitions for a perfect society, which could be made from different points of views. Human beings during the history always tried to create one of these communities as groups, countries, tribes, etc, and because of different reasons its effort could not have a brilliant result. I believe an ideal society is a place which all people have the same right and freedom regardless to their colours, religions, or ethnicities. it has a healthy and logical structures, which help the society to reach in a perfect relationship, and achieves its goal.
Nowadays, the most important issue for any person is living in an egalitarian society. All people should have the same right and freedom for the way they want to live. This right should be available for all members of society, regardless to their mode of thinking, belief, or race. In this way these people consider the society their own home and help to increase the quality and value of there. Now we can observe an influx of immigration from different nationality to different developed countries, which praise this value and equality and contribute on empowerment of those countries as their own country.
More over, an ideal community is a place where is build upon a healthy and logical structure. In such a place any kind of problem is each person problem and would be discussed within the members of the society regarding to their expertise, and the resolution come out by a healthy and open mind discussion from inside of that society. It can be clearly seen that in most of the developed countries, which led the main economical and technological powers in the last two centuries, the solutions for their problems came out from their own by smart decision based on their public opinions.
In a nutshell, although there could be a different definition for a perfect society, I believe a perfect society is one where all members have the same right and with freedom, so they easily can collaborate to plan and achieve their goal in order to make their future.
