What is the manifestation of inequality between people?

Inequality between people began to manifest itself in the primitive world. The reason for the emergence of wealthy and poor people was the difference in spheres of activity. Hunters, chieftains, and elders received more benefits because they were doing more responsible work. Inequality also existed in a slave society. The feudal regime was also built on the relationship between rich feudal lords and poor workers. The same trend is observed in the capitalist system. Someone has more capital, and someone less.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
