How I see it, the disparity has been growing and has reached a tipping point. And at this point in our human evolution there is two ways we can go, the path of isolationism, and wall building, which will inevitably lead to an extremely dark age of war and tension. Or we break down the walls between us and unite as the collective tribe of man and come together to heal the trauma we have created! It is inevitable that we will unite, it is just a matter of time. Be it now, tomorrow or a thousand years from now, or a million years from now in a different solar system, unification and integration is inevitable!
