People could all see that since the universe was not as empty as they had imagined, but filled with all kinds of wondrous life forms that had built societies even more prosperous than humanity's, humanity would eventually have to join them. That would create countless social positions.
Relatively speaking, the issue of distribution among human individuals was still fundamentally a matter of insufficient total resources. While it was true that dividing Earth's resources equally could keep everyone alive, exactly what standard of living that would provide was hard to say.
Being fed, clothed, and having some entertainment was enough, certainly, but there would always be people with loftier aspirations. Even setting material conditions aside, fulfilling one's own value was humanity's highest emotional need.
And if Earth's existing resources were divided equally, there would inevitably be people unable to achieve the self-worth they desired. Conflict was therefore bound to arise.
So the best solution was not absolute fairness, but increasing the total amount while maintaining relative fairness, allowing even the poorest group to fulfill their needs to the greatest possible extent.
To achieve that, humanity would inevitably need to join interstellar society. Besides exploiting extraterrestrial resources, it could provide jobs for more people who needed them and opportunities for ambitious individuals to fulfill their own needs.
By then, people with higher-end needs could go outward, while those who did not want to leave could remain on Earth without facing such fierce competition. With the immense abundance of resources brought by interstellar development, it still might not be possible to completely eliminate the gap between rich and poor, but whether poor or rich, everyone would be moving forward overall. Life would definitely be better than before.
Most graduates of prestigious universities who had successfully become psychologists could see this clearly. Although they
