In a world so perfect, where there is no injustice, illness, insecurities and so many more, growth as a response to problems will not be considered necessary since there is actually nothing to worry about. Insecurities won't even come across the minds of the people so there would be no need to grow or build more sophisticated weapons to defend themselves.
But then humans are designed naturally to want to grow beyond their normal levels so growth won't be totally out of extinction but the focus changes to another thing entirely which is; growth would be channel or it shifts from survival mode to some sort of fulfillment. Since there are no more worries about mending things, learning to struggle for money, fulfillment would be a way of widening knowledge. Leave it or take, there most always be a set of people that would not want to just limit themselves for the regular comforts they get and would detest being same level of literacy with others so the need to not become ordinary would trigger a spark to know more.
Also, another level of creativity would be unlocked for a soft life not because something is wrong anywhere but because it is possible to do which is also a way for them to explore more. Also the world will still be dynamic because perfection does not me it would be stagnant. Honestly, there would be mad creativies compared to what we are seeing.
Although a perfect world once existed in time memorial in the garden where the first man and woman was created. They had everything they wanted and more. Ever since the fall a perfect world seems to be in extinction. Everything known as a perfect world, now leaves in our imagination. Majority of our leaders do not even care about her citizens as they are left to either survive or die. The world is now a jungle where it is survival for the fittest and only the fittest are safe. But then as a result of so many imperfections in our world today, it has led to so many meaning stuff. And that's why we enjoy most of the things we enjoy today such as science and its numerous inventions and among others.
So many stories to inspire. Wait? I think the world isn't meant to be perfect because so many people have risen beyond their abilities as a result of inspired stories they heard from others making them believe in their own selves.
Lastly, leaving in our current reality and seeing all that is happening, a perfect world is almost impossible but what we truly desire is a world of meaning. A world of true meaning would ease so many burdens where everything is transparent before the people and resources channeled to the right purposes.
