The assay argues that the Equality-Inequality dialectics is a very complex issue,which reflects many social dilemmas.On one side are the state official commitments to secure,maintain and protect all kinds of formal equalities.On the other side are the natural and genetic distinctions that differ between human-beings while creating and maintaining inequality.In fact,this is kind of a contradiction exists in many fields of social sciences.The essay’s author reviews some of the relevant historical events,such as social mobility,individualism and education and points out on future solutions.Among the proposed suggestions are:1)Embracing Frankl’s giving“Meaning to Life”as a leverage for increasing pleasure of life;2)Recognizing and promoting Creative Individualism as the legitimized ground for inequality;3)Increasing Social Cohesion,required for social empowerment and attaining security and happiness. 展开更多
