Society's Three Personality Classes

It seems that society can be broadly divided into three personality types. All three personalities manifest to some degree in every individual, but most individuals seem to fall into one of these categories. These three personalities also parallel the class systems of traditional societies.

Priests view life as a relationship to be experienced and known. They define success as having deep relationships with and knowledge about life and people. Priests are idealistic and driven by deeply held values. 

Aristocrats are focused on worldly success. They're often goal oriented and seek financial success, status, and power. People and relationships are secondary to whatever they seek to obtain.

Commoners make up the majority of society. They're content with moderate prosperity and pleasure. They don't generally challenge or even think much about the status quo they live within. 

Priests and aristocrats fight for power at the top of society. Both personality classes are strong willed, but they approach life from totally different perspectives, and they have different ideas about what constitutes social and personal success. The priests control society's values and culture while the aristocrats control most of its material hardware. Priests and aristocrats negotiate how society will operate and evolve while commoners either work quietly at the bottom or find themselves mobilized to fight for the interests of either the priests or aristocrats.

Everyone has a little of all three personalities within them, but some people are strongly characterized by only one of the three personality types. In my experience, it seems different societies have different personality mixes. The American population seems to have a higher percentage of priests and aristocrats while the vast majority of the Chinese population consists of commoners. 

The causes of this tripartite division are likely partially genetic as well as being strongly influenced by environmental factors. China's situation is interesting; the mainland population overwhelmingly falls into the commoner class, but the population of Hong Kong is strong willed (as the 2019 protests proved). For one thing, Hong Kong's population is far more religious than the mainland population which gives many of them an independent ethical standard by which they can judge the government of China. The mainland population, however, largely has no independent standard and is thus reduced to believing whatever their rulers tell them.
