As human beings we are basically all the same; after all we belong to the same planet, All sentient beings have the same innate nature that want happiness and don’t want to suffer. All of us need love and desire something good. As far as material development is concerned, we have already achieved a great deal with most nations on this planet aiming for better quality and a prosperous society.
We may eventually achieve this, however material development is not sufficient for human happiness. We need more than external object in order to be happy and well.
The most important thing in life is affection & love. Without love and affection we cannot achieve genuine happiness, for a happier life means happier relationships. Not just individual relationships but relationships in general. The key to happiness though is inner quality and a knowing, not necessarily the absence of suffering.
