In the free democratic societies that have mostly replaced authoritarian societies, the upper level is formed from the middle level and the middle level from the lower level. No one's position is permanently occupied, and there are no strong authoritarian forces blocking interaction and communication. Mutual understanding isn't difficult.
現在民主自由社會大多已取代了威權社會，上層是由中層出現，中層是由下層出現，每個人的位置不是永久佔領著，也沒有強烈的威權型態防礙交流、溝通，上下通達並不困難。
