A concept that I find fascinating is the human tendency to attempt to collectivize as a solution to problems or a desire to have companionship. In some areas this may relate to introversion and extroversion, in others not.
I know the word "Communism" is horrible but from one perspective, Communism just appears to me to be a form of governing that deteriorates in usefulness the more people it involves. The basic ideas behind Communism are actually very functional in a small family situation whereby each member of the family can keep track of each other member. Each member does what they can according to their ability and each member takes what they need based on their unique individual needs. Sharing without personal greed or selfishness is paramount in family situations. If we move up to local community levels, we start to see the deterioration of the usefulness of collective cooperation but some elements are still there. Neighbors keep an eye on others' houses to help avoid crime, trust is reciprocal and people who know each other still share to some extent with the expectation that those they share with will reciprocate. In employment, there is similar sharing of collective interests especially as the employer is smaller rather than larger.
We then go to city, county, national and then international levels seeing how collective thought deteriorates more and more in value with each successive tier up.
While it seems that collectivism is worse the higher it goes, the tendency is for people to try to get more and more of it the higher it goes. Failures on family levels are heaped on community levels; failures on community levels are then heaped on city levels and so forth.
